High yield point, high hardness, significant cold hardening effect, prone to cracks and other defects
Thermal conductivity is worse than ordinary carbon steel, resulting in large deformation force, large punching force and deep drawing force required.
When deep drawing (stainless steel stamping), the forming deformation is hardened intensely, and the thin plate is easy to wrinkle or fall out.
Deep drawing molds are prone to adhesive tumors, causing serious scratches on the outside diameter of parts.
When drawing, it is difficult to get the desired shape. The above problems are determined by the performance of stainless steel itself, mainly affected by the following five factors: First, the performance of raw materials; Second, the structure and stamping speed of the mold; Third, the mold material; Fourth, stamping lubricating fluid; Fifth, the arrangement of the process route.
