Ti in 321 stainless steel exists as a stabilizing element, but it is also a heat-strength steel, which is much better than 316L in terms of high temperature. 321 stainless steel is in organic acids and inorganic acids of different concentrations and temperatures, especially in oxidizing properties. The medium has good abrasion resistance and is used to manufacture wear-resistant acid containers, linings of wear-resistant equipment, and pipelines.
321 stainless steel is a Ni-Cr-Ti austenitic stainless steel. Its performance is very similar to that of 304, but due to the addition of metallic titanium, it has better resistance to grain boundary corrosion and high temperature strength. The addition of metallic titanium effectively controls the formation of chromium carbide.
321 stainless steel has excellent high-temperature stress rupture (Stress Rupture) performance and high-temperature creep resistance (Creep Resistance) stress mechanical properties that are better than 304 stainless steel. Suitable for welding components used at high temperatures.
