On January 9th, the Stainless Steel Branch of the China Special Steel Enterprise Association announced the results of the online public vote for the top ten stainless steel news in China in 2022. It is expected that Chinas stainless steel production will reach 31.5 million tons in 2022, a year-on-year decrease of 3.5%, and will experience negative growth in the past decade. The following are the top ten news items for Chinese stainless steel in 2022 selected by the vote. Firstly, the SUS630 stainless steel cold-rolled plate of Taiyuan Iron and Steel Group has successfully replaced imports, solving the "bottleneck" problem in Chinas printed circuit board industry. On February 21, 2022, Taiyuan Iron and Steel announced that after nearly three years of system research and continuous improvement, Taiyuan Iron and Steel achieved stable supply of precipitation hardened SUS630 stainless steel cold rolled sheet products in bulk, becoming the first enterprise in China to provide such products. This product solves the "bottleneck" problem of key basic materials in Chinas electronic circuit industry, and helps Chinas electronic circuit printed circuit board industry move towards high-end. At present, the linear expansion coefficient, flatness, same plate difference, surface quality, and surface roughness of Taigangs products can meet the strict requirements of users.
