Precautions for stainless steel stamping processing

Pay attention to the following points in general stainless steel stamping processing:

1. High yield strength and tensile strength. Austenitic stainless steel has large work hardening and is prone to springback and cross-tool damage. Therefore, the humidity, stiffness and wear resistance of the processing plant equipment must be excellent, and it is usually selected Aluminum bronze (PVD, CVD surface treatment).

2. The heat conduction is small and the thermal expansion is large (Austenitic system), so choose water-soluble lubricating oil with excellent cooling performance. (Guide: What is stamping?)

3. Because some products often directly use the surface gloss of stainless steel plates, surface damage should be avoided during external pressure processing. In order to prevent surface defects and lubricate, usually the steel plate surface is vinyl coated or lubricated steel plate is used.

4. Austenitic stainless steel, the work hardening characteristics near normal temperature are greatly affected by temperature, and the formability is greatly affected by temperature and speed. Generally, under high temperature and high speed conditions, the value of n decreases and the molded parts deteriorate. Therefore, the use of temperature-affected warm processing methods can obtain extremely excellent stamping performance.
