Stainless steel precision strip

Stainless steel precision strip

Overview of the Precision Steel release:

Generally, stainless steel and heat-resistant cold-rolled stainless steel strips with a thickness of 0.01-1.5mm and a strength of 600-2100N/mm2 are defined as high-strength stainless steel precision steel strips. This kind of cold-rolled stainless steel strip with a thickness in the range of 0.3-1.5mm is defined as a high-strength stainless steel precision steel strip. Rolled steel strips (slitting and slitting) have overlapping positions in size, but only specially rolled and slitting products can meet the special requirements of precision steel strips.

Features of cold-rolled precision stainless steel strip:

Precision stainless steel strips have higher mechanical properties, surface conditions, thickness tolerances, widths, cambers, and straightness than ordinary cold-rolled steel. In addition, due to the individual design features of the precision strip mold, precision stainless steel strips customized for customers are rarely available for other users. This has very high requirements for the production, sales series, and technical support of precision stainless steel strips, making it quite In general cold-rolled stainless steel strip.

Due to the high technical content of precision stainless steel strips, the added value of precision steel strips is much higher than that of ordinary cold-rolled stainless steel strips, especially for precision stainless steel strips with a thickness of ≤0.30mm, the price increase range of specifications is several times higher than that of ordinary stainless steel strips above 0.3mm times, the market price ranges from tens of thousands of yuan/ton to several million yuan/ton, and the price increase system for specifications is relatively stable.

Misunderstanding of stainless precision steel belt:

①Stainless steel precision steel strip is ultra-thin stainless steel strip or stainless steel strip with a thickness of less than 0.1mm.

This is a misunderstanding of most people’s understanding of stainless steel precision steel strips. Stainless steel precision strips can be graded for precision control, which can strictly meet the needs of different users. It pursues quality stability, high precision, and requires high precision in terms of mechanical properties. Precision is only recognized from its product thickness. The steel belt is one-sided.

② With the advanced 20-roller Sendzimir rolling mill, stainless steel precision steel strips can be produced.

Advanced rolling mill equipment is indeed a key unit for the production of precision steel strips, and plays an important role in the surface quality, thickness tolerance and mechanical properties of precision steel strips, but it cannot be said that the rolling mill is the only factor that defines product quality.

The precision steel strip production line must be a systematic production line formed by the optimized combination of equipment. Any equipment failure in any link will affect the product quality of the precision steel strip.

③On the basis of ordinary cold rolling technology, equipped with advanced equipment and excellent staff, the products produced should be called stainless steel precision steel strips.

From the perspective of precision control, product grade, quality requirements, etc., the production technology of precision steel strip cannot be replaced by ordinary cold rolling technology. However, some cold-rolled narrow strip factories use the signboard of precision steel strips. In fact, the products they produce show “low yield” to the needs of users, which causes unstable product quality to users, while the real precision steel strip factories It maintains a high yield rate and can provide downstream users with products of different specifications, performances and quantities in a timely manner.

④ The scale of the precision steel strip factory is assessed by its production capacity.

It is true that the production capacity of the fine strip factory cannot be compared with that of the traditional cold rolling factory, but the high added value of the product reflects the value. For example, the price of some refined strip products in Europe is 10 times or even dozens of times that of cold-rolled products.

To sum up, the precision steel strip is not a cold-rolled plate, let alone a modified rolling material. It has a special configuration of raw materials, equipment, technology, personnel, and management. Refined strips are not mass-produced, but rely on added value of technology; while cold rolling relies on added value of scale, and modified rolling materials rely on added value of processing. Therefore, there are essential differences in terms of equipment, raw materials, varieties, craftsmanship, and markets. The real high-precision stainless steel precision strip production is a high-precision, high-tech system engineering, that is: precision high-strength ultra-thin stainless steel strip = precise raw material + precise equipment + precise production process + precise organization and performance control + Sophisticated standards → used in precision industries.

Industrial layout characteristics of stainless steel precision strips:

China’s stainless steel precision strip industry has strong financial and technical orientation, making the precision steel strip industry cluster in the developed eastern regions, especially the Yangtze River Delta region.

Among them, there are dozens of precision steel strip enterprises in Jiangsu, Shanghai, and Zhejiang, accounting for 75% of the total number of precision strip enterprises. From the perspective of production capacity, the production capacity in Jiangsu accounts for 13.5% of the total production capacity in the country, and the production capacity in Zhejiang occupies the national total. 20.7% of the total production capacity, 5.71% of the national total production capacity in Shanghai, 39.9% of the national total production capacity in Jiangsu, Zhejiang and Shanghai, and a relatively high degree of industrial concentration. Other enterprises are distributed in more economically developed areas such as Beijing, Shandong, and Liaoning. The production capacity in North China accounts for 7.14% of the total production capacity in the country.

The layout of China’s stainless steel precision strip industry has its inherent inevitability, probably due to the following points:

(1) The stainless steel precision strip industry is a technology-intensive and capital-intensive industry. In terms of industrial distribution, it tends to be in areas with a higher level of scientific and technological education, a deeper manufacturing level, and a large amount of surplus funds. Therefore, the eastern coastal areas are Become the first choice for precision steel strip manufacturers.

(2) Close to the consumer market and easy to export. The consumption industry of precision steel strips is mainly concentrated in high-tech industries such as electronic information industry and precision machinery, while the eastern coastal provinces and cities are far ahead of other regions in the country in terms of high-tech and manufacturing, making the eastern coastal provinces and cities the main consumers of precision steel strips market. In addition, the distribution of the precision steel strip industry in the eastern coastal provinces and cities is also convenient for the export of precision steel strips and the development of international markets.

(3) It is conducive to the outsourcing of raw materials. The production of precision steel strips generally adopts cold-rolled stainless steel coils with good quality. At present, China’s high-quality cold-rolled stainless steel coil manufacturers Zhangjiagang Pohang, Shanghai HY Industry Co., Ltd., and Taigang Stainless Steel are distributed by three companies. In Jiangsu, Shanghai, Shanxi. For example, Shanghai HY Industry Co., Ltd, a manufacturer of precision steel strips, settled in Wuxi to take full advantage of Wuxi Jiangyin’s raw material procurement advantages. In addition, precision steel strip production enterprises distributed along the coast are also convenient for importing cold-rolled stainless steel coils from South Korea and Japan.
