Good translation Metal Products (Shanghai) offers stainless steel (made of stainless steel / stainless steel imports) 321 stainless steel / steel 321 / 321 steel bar / 321 Coil / 321 steel / steel 321 / 321 wire (good translation Metal Products (Shanghai) Co., Ltd. ) 
 Outline 
 Austenitic stainless steel is equivalent to domestic 1Cr18Ni9Ti 
 U.S. grades for: 321, S32100, TP321 
 Japanese Grade: SUS321 
 British brands: 304S12, 321920 
 Germany Brand: X10CrNiTi189 
 Feature 
 321 stainless steel in which the Ti as a stabilizing element exists, but it is also hot and strong steel at high temperatures is much better than the .321 316L stainless steel in different concentrations and different temperatures of the organic acids and inorganic acids, especially in oxidizing medium has good corrosion-resistant performance, for the manufacture of wear-resistant acid containers and equipment lining, pipeline. 
 321 stainless steel is Ni-Cr-Mo austenitic stainless steel, its performance is very similar with the 304, but the incorporation of the metal titanium, it has a better resistance to grain boundary corrosion and high temperature strength. The addition of titanium to make it effective control of the chromium carbide formation. 
 321 stainless steel with excellent high-temperature stress rupture (Stress Rupture) performance and high-temperature creep resistance properties (Creep Resistance) stress mechanical properties are superior to 304 stainless steel.
