Product Description
1.4541 ASTM SS321 UNS S32100,Acero 321 Seamless Stainless Pipe Steel Tube ForBoiler pressure vessel
321 is a kind of Ni-Cr-Ti austenitic stainless steel, with good wear resistance, high temperature resistance, creep resistance, etc.Good wear resistance of 321 stainless steel is shown in different concentrations and different concentrations of organic and inorganic acids.Temperature, especially in oxidized media.At the same time, class 321 is also a refractory steel with higher temperature resistance than 316L.Its performance is very similar to that of the 304;However, due to the addition of Ti as a stable element, 321 stainless steel has better high-temperature strength and intergranular corrosion resistance, so it can effectively control the formation of chromium carbide.
321 stainless steel has excellent high temperature stress fracture performance and high temperature creep resistance.Its stress mechanical properties are better than 304 stainless steel, suitable for welding parts under high temperature.
