Chromium-nickel austenitic stainless steel in the heating process there is no phase change occurs, the grain will swell, and ferrite precipitated in the heating process, to promote the corrosion resistance of austenitic stainless steel can be reduced. Therefore the corrosion resistance. Requirements of chromium-nickel austenitic stainless steel head by hot stamping molding, subjected to a solution heat treatment (S), the aim is to obtain a single, homogeneous austenite structure, having high corrosion resistance.
