Factory Directly Supply Stainless Steel Pipe SUS 321 Seamless Stainless Steel Pipe Tube
321 stainless steel is a material with excellent high temperature stress rupture and high temperature creep resistance, and its stress mechanical properties are better than 304 stainless steel.
Equivalent to Chinese grade 0Cr18Ni10Ti 321 stainless steel, it is Ni Cr Mo austenitic stainless steel. Its properties are very similar to 304, but due to the addition of metal titanium, it has better grain boundary corrosion resistance and high temperature strength. Due to the addition of titanium, the formation of chromium carbide is effectively controlled.
321 stainless steel pipe has good corrosion resistance in the atmosphere and is widely used in petrochemical, electric power, bridge, automobile and other industries.
