Stainless steel SUH409L and 441 for automobile exhaust pipes of Benxi Steel successfully rolled off the assembly line
A few days ago, after intensive preparations, the first batch of stainless steel SUH409L and 441 special for automobile exhaust pipes after the resumption of production of Benxi Steel Dandong Stainless Steel Co., Ltd. was successfully rolled off the assembly line, and the appearance and mechanical properties met the needs of users, reaching the advanced level of similar products, and available in batches. Supply Capacity.
Since the second half of this year, Benxi Steel Dandong Stainless Steel Co., Ltd. has thoroughly implemented the work requirements of the Benxi Steel Group on reducing losses and turning losses. The group is led by the leaders of the group, and the relevant personnel of the International Trade Company, the Plate R&D Institute, and the company have gone to external market research and reached agreements with relevant users.

Therefore, this steel has higher requirements on the composition of raw materials. During the rolling process, the company strengthened the control of process parameters, combined with the characteristics of tropical pickling board raw materials to strictly control the surface quality and impurities, and rationally optimized the technical process parameters and operating skills of abnormal conditions, and obtained the approval from Angang (Guangzhou) Lianzhong With the full support of the company, on this basis, a complete set of production technology has been formed.
At present, the company’s SUH409L and 441 have stable supply capacity for batch rolling, and the trial rolled coils have been successfully rolled off the production line.
