Ti in 321 stainless steel plate exists as a stabilizing element, but it is also a heat-strength steel type, which is much better than 316L stainless steel plate in high temperature. 321 stainless steel plate is in organic acids and inorganic acids with different concentrations and different temperatures, especially It has good abrasion resistance in oxidizing media, and is used to make linings and pipelines for wear-resistant acid containers and wear-resistant equipment.
321 stainless steel plate is Ni-Cr-Mo austenitic stainless steel plate, its performance is very similar to 304 stainless steel plate, but due to the addition of metal titanium, it has better resistance to grain boundary corrosion and high temperature strength. The addition of titanium metal effectively controls the formation of chromium carbide.
The 321 stainless steel plate has superior Stress Rupture performance and high temperature Creep Resistance stress mechanical properties than the 304 stainless steel plate.
