What is the cold rolling process of stainless steel?

After the hot rolling of stainless steel, some hot-rolled stainless steel products are directly used downstream, and some hot-rolled products need to be processed into cold rolling before use. In this issue, ferote will introduce the cold rolling process of stainless steel to you, hoping to help you.

Cold rolling of stainless steel, hot rolled stainless steel products with a thickness of 3.0-5.5mm are mostly used. After calendering by cold rolling equipment, they are produced into cold rolled stainless steel products. At present, there are two main production processes for stainless steel cold rolling: stainless steel single stand cold rolling and stainless steel multi stand cold rolling. The specific production process is as follows:

After the cold rolling of stainless steel, it needs to be annealed and pickled. Annealing of cold rolled stainless steel is to eliminate work hardening and achieve softening through recrystallization; The purpose of pickling is to remove the oxide layer formed on the surface of steel strip during annealing, and to passivate the surface of stainless steel to improve the corrosion resistance of steel plate.
