In the use of stamping materials, stainless steel materials are mostly used. What should we know in advance about stainless steel stamping? Can we avoid unnecessary situations from happening?

When processing stainless steel stamping, we need to pay attention to:

1. The problem of springback deformation in stainless steel materials occurs after stretching and forming. Due to the high hardness of stainless steel, the rebound of the material is significant. When designing the forming mold, it is necessary to estimate the rebound value of the material and minimize the size problems caused by material rebound.

2. Regarding the issue of heat treatment, many stainless steel stamping and stretching parts have high hardness requirements. However, the harder the material, the greater the difficulty of stretching. Sometimes, it is necessary to perform heat treatment after forming to meet the hardness requirements. However, the stamped parts after heat treatment are prone to deformation, and the amount of deformation needs to be considered in mold design. Selection of cutting tools: Stainless steel has high hardness and will cause relatively large wear on the mold cutting edge. Therefore, when selecting cutting tools, it is necessary to make appropriate choices based on the hardness of the stainless steel material.

3. The selection of stainless steel stamping oil: The selection of stamping oil should be cautious. Suitable stainless steel stamping stretching oil must contain sulfur chlorine composite additives to prevent problems such as hardening, deformation, burrs, and breakage of stamped parts. For the ease of cleaning of stamped parts, we can choose low viscosity stamping and stretching oil.

In addition, during stainless steel stamping, there may be scratches on the surface, cracks in the stamped parts, and problems with the mold material.
