What is the difference between stainless steel 304 and 321 material
321 stainless steel: It is Ni-Cr-Ti austenitic stainless steel. 321 stainless steel is Ni-Cr-Ti austenitic stainless steel, its performance is very similar to 304, but due to the addition of titanium metal, so that it has better resistance to grain boundary corrosion and high temperature strength. Due to the addition of titanium metal, it effectively controls the formation of chromium carbide.
