Material: 321 Surface: NO.1 / 2B Uses: Boiler shell heat exchanger, furnace parts Specifications: Complete specifications Origin: TISCO, Baosteel, Jiuquan Product Overview austenitic stainless steel grades for the equivalent of US domestic 0Cr18Ni10Ti: 321 , S32100, TP321 Japanese Grade: SUS321 English Grade: 304S12,321920 Germany Grade: X10CrNiTi189 321 Ti stainless steel which exist as a stabilizing element, but it is also heat resistant steel at high temperatures is much better than the 316L stainless steel .321 different concentration and temperature of organic and inorganic acids, especially with good abrasion performance in oxidizing medium, for the manufacture of wear-resistant and wear-resistant acid container lining equipment, pipelines. 321 stainless steel is Ni-Cr-Ti-type austenitic stainless steel, its performance is very similar to the 304, but due to the addition of titanium, it has a better intergranular corrosion resistance and high temperature strength. The addition of titanium, making it effective control of the formation of chromium carbides. Excellent high temperature stress of 321 stainless steel with a breaking (Stress Rupture) properties and high temperature creep resistance (Creep Resistance) stress mechanical properties are superior to 304 stainless steel.
