The 321 stainless steel tube is a Ni-Cr-Mo type austenitic stainless steel tube. Its performance is very similar to that of the 304 stainless steel tube, but due to the addition of metallic titanium, it has better resistance to grain boundary corrosion and high temperature strength. Due to the addition of metallic titanium, it effectively controls the formation of chromium carbide.
321 stainless steel tube has excellent stress Rupture performance and high temperature resistance (Creep Resistance) stress mechanical properties are better than 304 stainless steel tube.
