Parts Forming Cold-rolled Steel Plate

When parts forming cold-rolled steel plates are used for parts forming, the plastic deformation degree of the material is required to be large, and the surface must not have parts with wrinkles, cracks, etc. For different parts, use different grades of steel plates. For example, the standards of Japanese automobile steel sheets are divided into three categories.
