Corrosion resistance and main use environment：321 stainless steel is a Ni-Cr-Mo austenitic stainless steel, its performance is very similar to 304, but due to the addition of metal titanium, it has better resistance to grain boundary corrosion and high temperature strength. Due to the addition of titanium, it effectively controls the formation of chromium carbide.
