321 stainless steel in which Ti exists as a stabilizing element, but it is also a hot-strength steel species, in the high temperature is much better than 316L. 321 stainless steel in different concentrations, different temperatures of organic acids and inorganic acids, especially in the oxidation The medium has good abrasion resistance and is used to make linings and conveying pipes for wear-resistant acid containers and wear-resistant equipment.
321 stainless steel is a Ni-Cr-Ti type austenitic stainless steel, its performance is very similar to 304, but due to the addition of metallic titanium, it has a 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 has excellent stress Rupture performance and high temperature creep resistance (Creep Resistance) stress mechanical properties are better than 304 stainless steel.
