Precautions for stainless steel processing and construction
Cutting and punching Since stainless steel is stronger than ordinary materials, higher pressure is required during stamping and shearing. Only when the gap between the knives and knives is accurate can shear failure and work hardening not occur. It is best to use plasma or laser cutting. When ga...Read more -
Three hardness standards for steel
The ability of a metal material to resist the indentation of the surface by hard objects is called hardness. According to different test methods and application scope, hardness can be divided into Brinell hardness, Rockwell hardness, Vickers hardness, Shore hardness, microhardness and high temper...Read more -
