321 STAINLESS STEEL PLATE

Is used in the chemical, coal, petroleum industry field open-air machinery, building materials, heat-resistant parts and heat treatment of parts with high resistance to corrosion requirements of the grain boundaries.

321 stainless steel plate in which Ti exists as a stabilizing element, but it is also a hot strong steel, in high temperature than 316L stainless steel plate is much better. 321 stainless steel plate in different concentrations, different temperatures of organic and inorganic acids, especially in oxidizing media with good resistance to wear and corrosion, used in the manufacture of wear-resistant acid containers and wear-resistant equipment lining, conveying pipeline.

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 titanium, so that it has a better resistance to grain boundary corrosion and high temperature strength. Due to the addition of titanium metal, so that it effectively controls the formation of chromium carbide.

321 stainless steel plate has excellent high temperature stress breaking (Stress Rupture) performance and high temperature resistance to latent change performance (Creep Resistance) stress mechanical properties are better than 304 stainless steel plate.
