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.
