TP321 stainless steel pipe is an American grade.
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 high temperature. 321 stainless steel is in organic acids and inorganic acids with different concentrations and different temperatures, especially in oxidizing 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 Ni-Cr-Ti austenitic stainless steel, its performance is very similar to 304, but due to the addition of titanium metal, it has better resistance to grain boundary corrosion and high temperature strength. The addition of titanium metal effectively controls the formation of chromium carbide.
321 stainless steel has superior Stress Rupture performance and high temperature creep resistance stress mechanical properties than 304 stainless steel.
