What is an optical fiber cable harness?

With the rapid development of the automobile industry, the complexity of the automobile electronic system is increasing, and the requirements for the communication system are becoming increasingly strict. As an advanced signal transmission carrier, optical fiber wiring harness is widely used in automobile industry. Optical fiber, with its advantages of high speed, high reliability, low loss and anti-electromagnetic interference, is gradually changing the data transmission mode of automobiles, and has shown great application potential in the field of automotive communication. In this paper, the basic characteristics of fiber optic wiring harness and its application in automobile are discussed, and its advantages and development prospects are analyzed.

 Optical Fiber Cable

With the intelligent and connected automobile technology, the demand for communication and data transmission is increasing day by day, and the security and stability of vehicle electronic communication system has become the focus of research. As an advanced communication technology, optical fiber communication technology provides a new idea for the development of vehicle electronic communication system. This paper analyzes the characteristics of optical fiber communication technology, analyzes the application of optical fiber in the future automobile from many aspects, discusses its advantages, and looks forward to its development trend.

 

 

Technical overview of optical fiber wire harnesses

Optical fiber cable harness uses light wave as carrier and optical fiber as transmission medium. It has the advantages of high speed, high reliability, low loss and anti-electromagnetic interference. Its transmission rate is much higher than that of traditional copper wire or coaxial cable, which can meet the communication needs of vehicle systems for large data volume and high real-time. The link of optical fiber communication mainly consists of optical connector and optical fiber carrier to realize high-speed signal transmission.

 

1.1 Optical Fiber Connectors

Optical fiber connector is an optical passive device that realizes the active connection between optical fibers. It is mainly composed of optical fiber reinforcement, optical fiber alignment, elastic docking, head lock, optical cable fixing, pin anti-rotation, and optical cable buffering. Optical fiber connectors usually use ceramic pins and ceramic bushing for optical fiber alignment, and spring ensures elastic butt on the end face of the pins. The spring is in the pre-compression state before docking, so that the locking force of the pins will not move. During docking, the pins will produce secondary compression due to the back of the pins, and the elastic force will be fed back to the pins, so that the two pins of the docking are always in the stress contact and compression state during the docking process.

 Fiber Optical Cable

1.2 Optical Fiber Conductor

The cylindrical shape of the fiber is mainly composed of the core, cladding, and coating layer. The transmission principle of optical fiber uses the phenomenon of total reflection of light, that is, when the light is incident from the optically dense medium (relatively high refractive index) to the optically sparse medium (relatively low refractive index), if the incidence Angle is greater than the critical Angle of total reflection, the light will no longer refract, but all reflect back to the original medium, ensuring that the optical signal can spread in the fiber without leaking out.

 Fiber Optical Cable

The optical fiber has the following features:

(1) Transmission speed, distance, content: the transmission speed of optical fiber is very fast, can transmit data to a long distance, and can transmit a large amount of data at the same time.

(2) Free from electromagnetic interference: The optical fiber transmits the optical signal, which is not interfered by electromagnetic waves, so the signal quality is more stable.

(3) Bandwidth: Optical fiber has a very wide frequency band, which can support high-speed data transmission.

(4) Low loss: The transmission loss of optical fiber is very low, and it can theoretically transmit hundreds of kilometers or even more without losing signal quality.

(5) High security: the optical fiber transmission signal will not produce electromagnetic radiation, nor will it be eavesdropped by external electromagnetic waves, so it is more suitable for some scenarios with high data security requirements.

(6) Small size and light weight: Optical fiber is smaller and lighter than traditional copper cables, convenient deployment and maintenance, especially in large-scale communication networks, this advantage is more obvious.

 

 

Advantages of optical fiber harness in automotive intelligent application

When the transmission rate of copper wire reaches more than 10 GB/s, it will be necessary to use thicker copper wire to meet the speed requirements, but in the arrangement environment of the car, the thickening of the copper wire has brought about the increase of the weight of the vehicle and the increase of the cost of the car, which can not meet the requirements of the arrangement environment of the vehicle with high speed and low weight. The fiber optic wiring harness technology can significantly improve the quality and reliability of communication, reduce electromagnetic interference, and at the same time, improve the safety and stability of the vehicle without additional weight.

 

(1) The transmission rate of optical fiber cable harnesses is much higher than that of traditional copper wires or coaxial cables, and millions of megabytes of data can be transmitted per second, which can meet the communication needs of modern vehicles for large amounts of data and high real-time. The maximum speed of the traditional copper wire network can only reach 10GB/s, which is difficult to meet the requirements of high-speed transmission.

(2) The transmission loss of optical fiber is extremely low, and the loss per kilometer is usually less than 0.0035 dB/m, which can ensure that the signal still maintains a high quality during long-distance transmission. In contrast, the transmission loss of the traditional copper wire network is 0.5 dB/m, and the loss is large in the long-distance transmission process.

(3) Optical fiber communication technology uses light waves to transmit signals in optical fibers, which has significant immunity to electromagnetic interference compared with traditional copper wire transmission.

(4) Compared with traditional metal wires, Plastic Optical Fiber (POF), as a kind of automotive optical fiber, can significantly reduce vehicle mass and improve vehicle economy.

 

The application of fiber optic wiring harness technology in automobiles not only improves the quality and reliability of communication, but also helps to reduce the overall weight of the vehicle, improve fuel efficiency, and adapt to various extreme driving environments.

2024 Second Half of the Year Import Iron Ore Continues to Maintain a Strong Supply and Weak Demand Pattern

 

Import Iron Ore Market Outlook for the Second Half of 2024

The first half of 2024 witnessed a fluctuating trend in imported iron ore prices, which initially declined, then rebounded, and finally fell again, ending the period lower than at the beginning, reflecting a slight overall decrease. As of June 28, the 62% Australian fines futures price index stood at $106.6 per dry metric ton, a decrease of 25.45% from the beginning of the year, while the 62% port spot price index was at 107.79 yuan/ton, down by 23.06% from the start of the year. The port spot price drop was less than that of the futures, leading to varying degrees of expansion in import profits for different grades. Concurrently, the Shanghai rebar price was 3480 yuan/ton, with a 13% decrease from the beginning of the year, showing that the finished product price drop was less than that of iron ore, indicating a weaker ore and stronger materials market situation. The basic supply and demand situation for iron ore in the first half of the year was characterized by a strong supply and weak demand pattern.

Price Review

The iron ore price in the first half of 2024 traced an inverted "N" shape, with a general downward trend, where the iron ore price drop was greater than that of the finished products. The 62% Australian fines index recorded a total drop of 25.45%, while the Shanghai rebar price saw a total decrease of 13%. As of June 28, the 62% Australian fines index was at $106.6 per dry metric ton, the 62% port spot index was at 107.79 yuan/ton, and the Shanghai rebar price was at 3480 yuan/ton.

Phase 1: January 2 to April 5

During this period, the 62% Australian fines index fell from the highest annual price of $143 per dry metric ton to the lowest of $97.45 per dry metric ton, a drop of 32%. The iron ore price repeatedly fell due to the dual impact of supply exceeding expectations and demand recovery not meeting expectations. Additionally, the slow pace of resumption of production and work in the terminal real estate and infrastructure sectors led to negative feedback from finished products to raw materials, causing iron ore prices to fall from the highest level of the year to the lowest.

Phase 2: April 5 to May 22

The 62% Australian fines index rebounded from $97.45 per dry metric ton to $122.45 per dry metric ton, a rebound of 26%. Macroeconomic benefits and the release of real estate relaxation policies led to a significant improvement in terminal demand, with finished products maintaining a reduction. On the demand side for iron ore, pig iron maintained an upward channel, market sentiment improved, trading activity increased, and iron ore prices rebounded.

Phase 3: May 22 to June 28

From $122.45 per dry metric ton, the 62% Australian fines index adjusted to $106.6 per dry metric ton, an adjustment of 13%. At the end of May, the State Council mentioned the strict implementation of steel capacity replacement, and the continuation of crude steel production control in 2024, leading to a decline in iron ore prices. Entering June, with a reduction in macroeconomic good news and the iron ore trading logic gradually shifting to a weak fundamental, coupled with the obvious seasonal off-season characteristics of terminal demand, iron ore prices fell further.

Fundamental Review

Supply: Increased Production in the First Half of the Year, Slow Recovery of Overseas Demand

In the first half of 2024, the total global iron ore shipments amounted to 786 million tons, an increase of 34.78 million tons year-on-year, an increase of 4.6%. Among them, the shipments of Australian iron ore in the first half of the year were 466 million tons, a decrease of 100,000 tons year-on-year, while the shipments from Brazil were 178 million tons, an increase of 11.75 million tons year-on-year, and shipments from other countries were 143 million tons, an increase of 23.14 million tons year-on-year.

The reasons for this situation mainly lie in: the Australian mines were affected by weather and accidents in the first half of the year, coupled with the new production projects in Australia not reaching the expected capacity; Brazil was relatively less affected by weather, and the mines increased capital expenditure on facility upgrades and maintenance, helping to increase production and shipments; the impact of accidents and geopolitical conflicts on non-mainstream countries has relatively weakened, with Ukraine, South Africa, and India contributing significantly to the increase.

Demand: Gradual Recovery of Pig Iron Production in the First Half of the Year, Steel Mills Continue Low Inventory Strategy

According to the Mysteel 247 blast furnace pig iron data, the total pig iron production in the first half of the year reached 415 million tons, a decrease of 14.46 million tons year-on-year, a drop of 3.36%, with an average daily pig iron production of 2.2821 million tons/day, a decrease of 92,500 tons/day year-on-year. It is clear that this year's pig iron production has been relatively weak compared to the same period last year, mainly due to poor performance in the downstream demand side. The inventory of finished products only began to decrease in mid-March this year, later than most years. At the same time, the increase in inventory pressure has led to increased losses for many steel mills, and the frequency of blast furnace maintenance has increased. Compared with the decline in crude steel in the first half of the year, it was found that the decline in pig iron was higher than that of crude steel, largely due to a significant recovery in scrap steel consumption this year.

Inventory: Continuous Accumulation of Port Iron Ore Inventory in the First Half of the Year

In the first half of 2024, the port inventory of imported ores first accelerated to a high level compared to the same period in the past three years, and then fluctuated at a high level. This year, the global iron ore supply and the annual comparison of China's iron ore arrivals have maintained a large increase, while pig iron production has been relatively weak year-on-year, so the port iron ore inventory level has expanded year-on-year in January-March, and from April to June, it has shown a continuous high level contrary to the trend of the previous two years.

Outlook

Overseas Supply

According to the seasonal pattern, the iron ore shipments in the second half of each year are higher than in the first half. Based on historical data, the second half of 2021 increased by 38.533 million tons compared to the first half, the second half of 2022 increased by 55.696 million tons, and the second half of 2023 increased by 75.493 million tons. This seasonal characteristic will continue this year. Considering the pace of new iron ore production projects globally and the annual sales and shipment targets of mines, it is expected that the iron ore shipments in the second half of this year will be 60.154 million tons higher than in the first half.

Domestic Supply

In the first half of the year, the domestic concentrate production was affected by previous accidents and weakened. Except for the Shanxi region, which is unlikely to resume production this year, some mines in Hebei have started to resume work. There were limited new production projects in the first half of the year, with a year-on-year increase of about 4.3 million tons in domestic concentrate production from January to May. In the second half of the year, despite the impact of winter mining difficulties and other factors, it is expected that some suspended enterprises will resume normal production, and there will be new production projects in the second half of the year. In summary, it is expected that there will be an increase of 2 million tons in domestic concentrate content in the second half of the year.

Domestic Demand

In the first half of the year, China's pig iron production decreased by 14.45 million tons year-on-year. For the calculation of iron ore demand in the second half of the year, four aspects need to be considered: first, the possibility of crude steel control policies being implemented in various regions within the year; second, the lack of domestic real estate policy drive; third, local efforts to resolve debt risks, and the slowdown in the development progress of infrastructure projects; finally, the United States, the European Union

300 Billion Market - High-Temperature Alloys Sector

 

High-Temperature Alloy Market - A 30 Billion Yuan Sector

Overview: Looking back at the price trend in the first half of this year, the stainless steel market operated with weak supply and demand, leading to a generally weak performance in prices. The balance of market supply and demand was disrupted, and production enterprises made production adjustments to cope with the current market conditions. Many companies have expanded their business to the high-temperature alloy field from 2020 to 2023. The output of high-temperature alloy steel of key Chinese enterprises was 15,900 tons, 22,300 tons, and 26,200 tons from 2020 to 2022, with a compound annual growth rate of 28.16% in the past three years. The global high-temperature alloy market size reached 38.239 billion yuan in 2023 and is expected to reach 56.767 billion yuan by 2029, indicating significant growth in the high-temperature alloy market in the coming years. Let's briefly understand the current situation of the high-temperature alloy market.

Definition of High-Temperature Alloy

High-temperature alloys are a class of metal materials based on iron, nickel, and cobalt that can work for a long time at temperatures above 600ยฐC and under certain stress; they have high-temperature strength, good oxidation resistance, corrosion resistance, good fatigue performance, fracture toughness, and other comprehensive performance. High-temperature alloys have a single austenite structure and exhibit good structural stability and reliability at various temperatures. Due to the above performance characteristics and the high degree of alloying, high-temperature alloys are also known as "superalloys" and are widely used in aviation, aerospace, petroleum, chemical industry, and naval vessels. Based on the matrix element, high-temperature alloys are divided into iron-based, nickel-based, and cobalt-based high-temperature alloys. Iron-based high-temperature alloys can generally only reach temperatures of 750-780ยฐC, while for heat-resistant parts used at higher temperatures, alloys based on nickel and refractory metals are adopted. Nickel-based high-temperature alloys hold a particularly important position in the field of high-temperature alloys, widely used to manufacture the hottest parts of aviation jet engines and various industrial gas turbines.

Price Trend Tracking

Looking back at the price trend of high-temperature alloys in the past two months, as of July 9th, the price of N08810 material from Anhui Fukai Resources was reported at 66,000 yuan/ton, a cumulative drop of 15,000 yuan/ton; the price of N08825 material was reported at 98,000 yuan/ton, a cumulative drop of 13,000 yuan/ton; the price of N10276 material was reported at 217,000 yuan/ton, a cumulative drop of 24,000 yuan/ton. It can be seen that high-temperature alloy resources are also showing a weakening trend, but even if the price weakens, the demand for materials such as N08810, N08825, and N10276 still shows a steady growth.

Features of High-Temperature Alloys

Excellent High-Temperature Strength: The ability to maintain high mechanical strength in high-temperature environments, ensuring the reliability of the material under extreme conditions.

Good Oxidation and Hot Corrosion Resistance: The ability to resist the erosion of oxidation and hot corrosion, extending the service life of the material.

Good Fatigue Resistance and Fracture Toughness: Possessing excellent anti-fatigue and fracture toughness, ensuring the safety and stability of the material during long-term use.

Sensitivity to Hot Working Processes: The microstructure of the alloy is very sensitive to hot working processes, requiring precise control of heat treatment processes to obtain the best performance and part quality.

Domestic High-Temperature Alloy Market Situation

The current situation of the domestic high-temperature alloy market is characterized by a large supply-demand contradiction but has huge development potential.

On July 10th, the domestic steel market fell. The Tangshan Qian'an general square billet ex-factory price including tax dropped by 20 to 3260 yuan/ton. In terms of transactions, the decline in futures prices has intensified the pessimistic sentiment in the market, slowing down the pace of terminal purchases, frequent low-priced resources, and the overall market transaction continued to decline.

๐Ÿ“ˆ Futures Price Movement

On July 10th, the main contract of rebar futures closed at 3478, a decrease of 0.91% from the previous trading day. The DIF and DEA overlapped, and the RSI indicator lines were between 28-40, operating between the middle and lower tracks of the Bollinger Bands.

๐Ÿ”จ Adjustments in Steel Mill Prices

On July 10th, 6 steel mills reduced the ex-factory price of construction steel by 20-30 yuan/ton.

๐Ÿ“‰ Daily Price Trends for Steel Grades

Rebar:

On July 10th, the national average price for 20mm Grade 3 earthquake-resistant rebar in 31 major cities was 3590 yuan/ton, a decrease of 19 yuan/ton from the previous trading day. In the short term, the current supply-demand contradiction cannot be fundamentally improved, and it is expected that the construction steel price will maintain a weak operation trend on the 11th.

Hot-rolled Coil:

On July 10th, the national average price for 4.75mm hot-rolled coil in 24 major cities was 3690 yuan/ton, a decrease of 14 yuan/ton from the previous trading day. Currently, the market is in a traditional off-season, and downstream rigid demand is difficult to significantly improve. On the supply side, most steel mills are at a break-even point, with no expectation of significant production cuts at present, and pig iron is at a relatively high level, with limited expectations for raw material purchases, and cost support is relatively weak. Overall, supply is strong and demand is weak, and it is expected that the price of hot-rolled coil will tend to be weak on the 11th.

Cold-rolled Coil:

On July 10th, the national average price for 1.0mm cold coil in 24 major cities was 4154 yuan/ton, a decrease of 13 yuan/ton from the previous trading day. The current off-season sales pressure on cold-rolled coil is gradually increasing, and with no significant reduction in supply, the inventory reduction speed is slow, and merchants can only choose to fall in price first to ensure transactions. In terms of mentality, the current spot market demand is flat, and merchants are cautious and slightly pessimistic about the future market. It is expected that the national cold-rolled coil spot price will be weak and stable on the 11th.

Plate:

On July 10th, the national average price for 20mm general plate in 24 major cities was 3727 yuan/ton, a decrease of 13 yuan/ton from the previous trading day. The market fluctuated downward throughout the day, the market mentality weakened, coupled with insufficient downstream purchasing strength, and the transaction performance of the whole day's plate was poor, with some market quotations slightly falling. In terms of resources, as prices adjust, the current North-South price difference has been somewhat repaired, but considering the poor market delivery, traders are not willing to stock up actively, and the amount of locked orders for North-South materials in the short term is relatively small. Overall, considering the poor demand performance, it is expected that the national plate price will continue to be weak and adjusted on the 11th.

๐Ÿ“‰ Daily Price Trends for Raw Materials

Iron Ore:

On July 10th, the prices of mainstream imported iron ore varieties at Shandong ports were weak and fell by 15-20 compared to the previous working day. On the seller's side, the enthusiasm of traders in the region to quote was average, mainly suitable for shipping, and there was little transaction in the spot market so far; the inquiry and offer sentiment in the Shandong distant month market was still acceptable, with a small amount of PB powder transactions at the end of August; on the buyer's side, some steel mills in the region replenished the warehouse as needed and maintained low inventory operations, with few inquiries. Currently, the mainstream of PB powder is between 808-813; the mainstream of super special powder is between 640-645; the mainstream of card powder is between 970-975 (unit: yuan/wet ton).

Scrap Steel:

On July 10th, the average price of scrap steel in 45 major markets was 2393 yuan/ton, a decrease of 6 yuan/ton from the previous trading day. Most of the steel mill's scrap purchase prices were adjusted downward, with an amplitude of 10-50 yuan/ton, while the base purchase price adjustment range was smaller. At present, the off-season characteristics are highlighted, the terminal demand for finished products is not good, and most areas are hot and rainy, restricting the pace of scrap steel transportation. The market has continued to decline, so the psychology of market merchants selling down and not selling up appears, and recently the arrival of scrap steel at steel mills and yards has improved. However, the difference between the waste board and the waste board continues to narrow, the steel mill is under pressure to increase production difficulty, and the scrap steel lacks cost-effectiveness compared to iron water. Therefore, overall, it is expected that the scrap steel market will continue to narrow down on the 11th, with an amplitude of 30-50 yuan/ton.

Coke:

On July 10th, the coke market price was temporarily stable. At present, the coke enterprises are mostly at a high level, some coke enterprises have approached full production, transportation and shipment are smooth, and the factory coke is running at a low inventory. On the raw material side, the price of coking coal fluctuates, and the procurement pace of coke enterprises is average, the market is still quite watchful, and the coke enterprises are cautious in procurement, maintaining low raw material inventory operations; downstream steel mill steel prices are weak, the transaction situation of finished products is not good, and the iron water output continues to rebound. The short-term coke market price is expected to be temporarily stable.

๐Ÿ”ฎ Steel Market Price Forecast

The weak trend of steel demand in the off-season is difficult to change, maintaining a weak supply and demand situation. Recently, the port inventory and port arrival volume of iron ore have continued to operate at high levels, especially the inventory of 45 ports is close to 150 million tons, and the supply and demand contradiction of iron ore has intensified, and the ore price has fallen from a high position. Due to the weak steel market fundamentals, the short-term steel price may continue to fluctuate and be weak.

Analysis of the Changes and Impacts of the New National Standard for Ribbed Reinforcing Bars in Hot Rolling

 

๐Ÿ“˜ Analysis of the Changes and Impacts of the New National Standard for Ribbed Reinforcing Bars in Hot Rolling ๐Ÿ“˜

On June 25, 2024, the State Administration for Market Regulation and the Standardization Administration of China officially released the new national standard "Steel for Reinforced Concrete Part 2: Ribbed Reinforcing Bars in Hot Rolling" GB 1499.2-2024. This is the sixth revision and will be implemented from September 25, 2024, replacing the previous national standard GB/T 1499.2-2018. This new standard is proposed by the Ministry of Industry and Information Technology and is executed by the National Technical Committee for Steel Standardization of Reinforced Concrete.

๐Ÿ” Key Technical Changes ๐Ÿ”

Compared to GB/T 1499.2-2018, in addition to structural adjustments and editorial changes, this new standard has made significant technical changes in terms of weight tolerance, fatigue requirements, inspection items, and sampling quantities.

๐Ÿ“ Terminology and Definitions ๐Ÿ“

The "shape and dimensional tolerances" have been adjusted, with the nominal rib spacing not exceeding 70% of the bar's nominal diameter. The weight tolerance has been tightened significantly, with 6-12 mm diameter bars allowed a deviation of ยฑ5.5%, 14-20 mm at ยฑ4.5%, and 22-50 mm at ยฑ3.5%.

๐Ÿ”จ Metallurgy and Performance ๐Ÿ”จ

For steel produced by converter or electric arc furnace, the new standard specifies that specific materials such as HRB500E, HRBF500E, HRB600 should undergo ladle refining. Higher nitrogen content is permitted in the "reinforcing steel chemical composition," promoting the development of high-strength reinforcing steel.

๐Ÿ”„ Fatigue Performance ๐Ÿ”„

New fatigue performance requirements have been added, particularly for concrete structures or components subjected to dynamic cyclic loading, such as highway culverts, railway culverts, and urban rail transit underground structures. The fatigue performance test should be conducted according to GB/T28900, with 5 samples taken from different bars (coils).

๐Ÿ”— Connection Performance ๐Ÿ”—

For HRB600 rebars, the new standard recommends mechanical connections and also allows for welding connections.

๐Ÿ— Surface Quality ๐Ÿ—

The new standard sets more refined requirements for the chemical composition and mechanical properties of rebars. If surface defects do not meet the mechanical or process performance requirements, the surface quality is deemed unqualified.

๐Ÿงช Test Methods ๐Ÿงช

The new standard updates the reverse bending test, allowing factory inspections to be conducted directly at room temperature. An additional reverse bending test sample is added for rebar grades with "E".

๐Ÿ“Š Weight Deviation Measurement ๐Ÿ“Š

The new standard is more precise, changing the total weight measurement accuracy from not greater than 1% of the total weight to accurate to 1 gram.

๐Ÿ“ฆ Packaging ๐Ÿ“ฆ

Besides the previous marking on the surface of the rebar with grade marks, manufacturer serial numbers, and nominal diameter millimeter numbers, the new standard allows for the marking of registered factory names or trademarks instead of the first two digits of the administrative division code. It also allows for the inclusion of barcodes and QR codes containing product information on the packaging, nameplates, and quality certificates of rebars.

Since the first release of the national standard for ribbed reinforcing bars in 1979, it has been revised every 5-10 years, and this is the sixth revision, 6 years after the last implementation date. The main changes in the new standard are as follows:

1๏ธโƒฃ For the rebar product itself, the new standard is more stringent in terms of weight tolerance, fatigue performance, surface quality, and weight accuracy, further improving the quality of rebar products.

2๏ธโƒฃ For production enterprises, to meet the technical requirements of the new standard, they may need to upgrade or transform production equipment or invest in research and development, which will increase production costs. Additionally, the new fatigue performance and sampling tests will increase the investment in rebar testing, further increasing operational costs.

3๏ธโƒฃ For high-strength rebar grades, the new standard requires the addition of ladle refining processes and welding connection methods, which will greatly improve the quality and performance stability of high-strength rebars.

4๏ธโƒฃ For the market itself, the implementation of the new standard will increase production costs in the short term and also improve the quality of rebar products. With the improvement of standards, the market demand for high-quality rebar will increase, and rebars that meet the new standard will be favored by users, with a certain quality "premium".

5๏ธโƒฃ The new standard is a mandatory standard that must be implemented. Production enterprises should familiarize themselves with the changes in the standard and adjust production processes before the standard is implemented. Considering the inventory digestion cycle, old standard rebar products accumulated by distributors after the implementation of the standard cannot be sold.

6๏ธโƒฃ Faced with the challenges and opportunities brought by the new standard, steel production enterprises should accelerate production technology transformation in the short term to meet the strict requirements of the new standard; at the same time, they should plan production reasonably, and balance the inventory structure of old and new products at the beginning of the standard implementation.

7๏ธโƒฃ The implementation of the new standard will undoubtedly bring profound changes to China's rebar industry. Although in the short term, rebar enterprises may face the dual pressures of rising costs and market adjustments, in the medium and long term, this standard may promote related production enterprises to improve product quality and safety, create a standardized and orderly market environment, and is conducive to building a modern industrial system that is autonomously controllable, safe and reliable, and has strong quality competitiveness, promoting the industry to the high end. With technological innovation to consolidate the core competitiveness of products, accelerate the transformation to high-end, green, efficient, and intelligent, and then achieve high-quality development and improve the overall competitiveness of the industry.

Baogang Mass-Produces Ultra-Long Wind Power Steel for the First Time

 

Baogang's First Batch of Ultra-Long Wind Power Steel Successfully Delivered

In early July, Baogang Steel's wide and heavy plate production line successfully produced and delivered an ultra-long wind power steel with a length of 18.8 meters to customers. This marks the first batch production of ultra-long wind power steel by Baogang Steel.

As a clean source of energy, wind power plays a significant role in the adjustment of China's energy structure, and the accelerated layout of clean energy has driven a strong market demand for wind power steel products. Baogang Steel is one of the earliest companies in China to develop wind power steel, and the thin plate factory's wide and heavy plate production line is the production line with the highest output of onshore wind power steel in China. After more than ten years of research and production, Baogang Steel's wind power steel has long become a well-deserved "punch product". In recent years, to enhance power generation, the blades of the "big windmill" have gradually become longer, and the height and diameter of the wind power tower that matches it have also increased accordingly. As the raw material for the production of the tower, the wind power industry's requirements for the length of wind power steel have also changed accordingly. Ultra-long wind power steel with a length exceeding 17.5 meters has a broad market prospect. Baogang Steel quickly targets the ultra-long wind power steel market and strives to expand the range of product specifications.

It is reported that after the first batch of ultra-long wind power steel was delivered to the users, it received good feedback, and other such products are being organized for production. The "upgrading" of Baogang Steel's wind power steel has further consolidated its position as a "punch" product, laying a solid foundation for enhancing market competitiveness.

Baosteel Group's Factory Prices Mostly Down in August Amid Downstream Order Deviation and Increased Competitive Pressure

 

๐Ÿ“‰ Baosteel Group's Factory Prices Mostly Down in August Amid Downstream Order Deviation and Increased Competitive Pressure

According to My Steel Network, in August, the ex-factory prices of Baosteel Group have largely been reduced based on the prices in July. This price adjustment is mainly to cope with the domestic off-season consumption, and the pressure to order has increased. Especially for some core varieties, the impact is relatively large, making it difficult for prices to show a rebound pattern.

๐Ÿ” Product Perspective

The entire series of hot-rolled products are under high pressure. The core issue is still that the profit from black goods is still stronger for sheet products than for long products. Therefore, the consumption pressure on hot-rolled, cold-rolled, and galvanized products rises during the off-season, forming a situation where supply does not decrease, demand declines, profits are positive, and supply and demand are loose.

๐Ÿ“Š Price Adjustments

  • Thick plate base price down by 100;
  • Hot-rolled base price down by 100;
  • Pickling base price down by 100;
  • Non-oriented silicon steel base price unchanged;
  • General cold base price down by 100;
  • Hot galvanized base price unchanged;
  • Electro-galvanized base price unchanged;
  • Medium aluminum zinc-aluminum magnesium base price down by 100;
  • High aluminum zinc-aluminum magnesium base price unchanged;
  • Aluminum-plated zinc base price unchanged;
  • Color coating base price unchanged.

For August, the hot-rolled Q235B tax-inclusive base price is 5302.85 yuan/ton; cold-rolled DC01 tax-inclusive base price is 8154.29 yuan/ton; hot galvanized DC51D+Z tax-inclusive base price is 8934.73 yuan/ton; silicon steel is 6038.6 yuan/ton (the above are estimated prices, the actual prices are subject to the price list).

๐Ÿ“ˆ Order Pressure and Market Outlook

Baosteel Group's orders in August are under greater pressure compared to July. In addition to domestic trade pressure, the decline in overseas prices has led to an increase in export order pressure. Downstream orders are not abundant, and currently, they are only replenishing inventory without hoarding and speculative behavior. This is the core issue of the lack of global liquidity, which makes it difficult for demand to rebound.

Looking at the next month, whether the price will remain stable depends on more factors, and we will also make a rough analysis:

1๏ธโƒฃ High Interest Rates Abroad and Liquidity Pressure

The Federal Reserve's interest rate cuts have not decreased, which has suppressed liquidity overseas, especially in countries with a shortage of foreign exchange, causing a suppression of purchasing power. From the current U.S. data, the core PCE continues to operate at a high level, and the core inflation has not decreased. Employment is relatively poor, making the probability of short-term interest rate cuts still maintained, but it is difficult to land. The difficulty of interest rate cuts before September continues to be maintained, making global liquidity continue to be compressed, making it difficult to release overseas purchasing power, and export pressure still exists.

2๏ธโƒฃ Off-Season Consumption and Difficult Recovery Expectations

Entering the off-season consumption of the manufacturing industry in July, the Mysteel survey shows that the manufacturing industry's inventory still needs a longer time to be digested, so it is difficult for domestic consumption to rebound in the short term, which is still low for downstream procurement enthusiasm. Looking at the PMI structure, the order on hand is low, and it is difficult for new orders to increase, and the support strength of rigid demand is poor without obvious policy introduction. For domestic consumption in August, the variable is not large, and exports are still in a supporting situation, making it difficult to appear rapidly.

3๏ธโƒฃ Profit Still Exists, Supply is Difficult to Decrease, and the Supply and Demand Structure Continues to be Loose

In July, the steel mill maintenance volume was flat compared to June. Currently, the maintenance expectation in July has been postponed, and the increase in new production lines has also increased. In addition, the profit of deformed steel bars is negative, and the profit of hot-rolled coils is positive, which also makes the output bias more clear. At present, the point-to-point profit of the steel mill is maintained at 40-50 yuan/ton, although it has been greatly compressed, but it can still maintain production, and the short-term reduction expectation will appear. Therefore, the output is maintained at a high level, and the consumption off-season pressure appears, and the supply and demand contradiction in July is still large, and the contradiction in August may continue to accumulate, which is difficult to support the confidence of the downstream.

๐Ÿ“ Conclusion

Overall, the base price of Baosteel Group in August has been reduced, and the main core contradiction comes from the domestic consumption off-season and the gradual pressure of overseas exports. Secondly, the output is maintained at a high level, causing inventory to accumulate. At present, the supply and demand contradiction is under seasonal pressure, and corporate procurement is cautious, with low orders on hand, and the supply is strong and weak pattern is reflected.

Based on this reason, it is difficult for the factory price of the steel mill in September to rise until the supply and demand are balanced, and the inventory shows a de-stocking structure.

Despite Rising Shipping Costs, U.S. Imports of Cold-Rolled Stainless Steel Surge

 

US Cold-Rolled Stainless Steel Imports Surge Despite Shipping Costs

According to the US Metal Miner on July 8, 2024, the overall Stainless Steel Monthly Metal Index (MMI) has reversed its downward trend, falling by 10.88% from June to July.

Nickel prices suffered significant losses in June, with a drop of over 14%, earning the title of the worst-performing base metal. Prices have fallen by more than 19% from their peak on May 20th, as they continue to search for a new bottom.

Bear Market Leads to a Significant Drop in Stainless Steel Prices

Throughout June, the bearish sentiment continued to echo in the stainless steel industry. Distributors and brokers reported an oversupply in the market, with buyers remaining uninterested in increasing their inventory.

Sources also indicated that the outlook for an improvement in demand is not optimistic. Although some still hope for a typical seasonal rebound in the fall, it seems unlikely to achieve year-on-year growth, as uncertainty remains a constant factor in the market.

Despite the gloomy outlook that has plagued the stainless steel market for over a year, steel mills continue to hold the base price. According to sources, steel mills do not believe that lowering the base price will translate into higher demand, giving them no incentive to formally adjust prices. Instead, steel mills plan to wait for the current market dynamics, hoping that buyers will return when the Federal Reserve begins to cut interest rates and more infrastructure projects start.

Despite Rising Shipping Costs, Cold-Rolled Stainless Steel Imports Still Increase

Despite weak demand, US cold-rolled stainless steel imports have surged since the end of 2023. The total monthly transaction volume jumped nearly 65% from the low point in November 2023 to the level in May 2024.

It is worth noting that the overall trend in April approached the level of 2021, which was when demand surged after the pandemic, forcing steel mills to start rationing due to supply shortages.

At first glance, the increase in imports is a strange phenomenon. The current market conditions in the US remain weak, and longer delivery times and higher shipping costs are considerable disadvantages for import demand.

Statistics show that from December 2023 to May 2024, the global container freight index soared by nearly 155%, eroding the competitive advantage of import prices compared to domestic counterparts.

Vietnam Follows Carbon Steel, Increasing Total Import Share

However, not every exporting country has experienced the same degree of increase. Further observation of the data shows that exports from Vietnam seem to have grown disproportionately.

Since 2018, the monthly imports from Vietnam have averaged about 5.77% of the total cold-rolled stainless steel imports. However, in April and May, Vietnam's share rose to 10.26% and 8.88%, respectively, approaching the level when China was still in the zero-COVID lockdown period. It is worth noting that carbon steel has also seen a similar trend since the beginning of 2024.

It is too early to say whether the increase in imports from Vietnam will become a sustained trend rather than a temporary anomaly. However, considering the country's issues, this may indicate China's dumping efforts.

Summary

Due to tariffs, cold-rolled stainless steel imports from China remain a negligible part of the total volume. However, China's share in the total volume has also increased. Since 2018, the average monthly imports from China have accounted for about 0.06% of the total volume. In the first five months of 2024, this average level jumped to 0.2%. Although China's total volume seems insignificant for the US domestic stainless steel supply and market impact, the disproportionate growth indicates that China's demand situation seems weak enough for prices to overcome US tariffs.

The remaining supply in China far exceeds the amount entering the US and what China can consume. This puts other countries like Vietnam in a difficult position. As Chinese materials continue to enter the global market, the constant result seems to be a negative impact on global prices.
