Introduce the processing techniques that affect the surface hardness of stainless steel strips
The processing technology that affects the surface hardness of stainless steel strips revolves around two main logics: "cold working deformation" and "heat treatment control". By changing the internal crystal structure of stainless steel strips (such as grain refinement and internal stress accumulation), their surface and overall hardness are directly determined. Among them, cold rolling process i
