Hot rolling and cold rolling 304 stainless steel forming process

Hot rolling and cold rolling are the process of forming steel or steel plate, they have a great impact on the structure and properties of steel, steel rolling is mainly based on hot rolling, cold rolling is only used for the production of small steel and sheet. Advantages of hot rolling: It can destroy the casting structure of the ingot, refine the grain of the steel, and eliminate the defects of the microstructure, so that the 304 stainless steel plate is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that…
