Related Description: 321 stainless steel is Ni-Cr-Mo type stainless steel, its performance is very similar with the 304, but because of adding the metal titanium, it has a better resistance to corrosion and high temperature strength of the grain boundary. The addition of titanium to make it effective control of the formation of chromium carbide. 321 stainless steel has excellent high temperature stress rupture (Stress Rupture) properties and high temperature creep resistance properties (Creep Resistance) stress mechanical properties are superior to 304 stainless steel.
