ASTM A312 321/316L/304 Stainless Steel Seamless Pipes And Tubes
HAOSTEEL is one of the most professional manufacturer and supplier of stainless steel Tube.Stainless steel tube can be divided into seamless tube and welded tube according to production mode. Seamless tube can be divided into hot rolled tube, cold rolled tube, cold drawn pipe and extruded tube.The welded pipe is divided into straight welded pipe and spiral welded tube.
Description:
Type 321 stainless steel is Ni - Cr - Ti austenitic stainless steel, abrasion Resistance, high temperature Resistance, Creep Resistance and so on, has the excellent high temperature Stress Rupture (Stress Rupture) properties and high temperature Creep Resistance (Creep to hold) using Stress mechanical properties suitable for high temperature welding structure, 321 stainless steel of Ti as a stabilizing element exists, better grain boundary corrosion Resistance and high temperature strength, the effective control of the formation of chromium carbide.
321 stainless steel has good abrasion resistance in organic and inorganic acids of different concentrations and temperatures, especially in oxidizing media.
321 stainless steel seamless steel pipe (gb14976-2002) is used to manufacture hot rolled and cold drawn (rolled) seamless steel pipe of high quality carbon structural steel for all kinds of structure low-medium pressure boiler superheated steam pipe, boiling water pipe and locomotive boiler superheated steam pipe, large pipe, small pipe and arch brick pipe.
The 321 stainless steel pipe has high endurance strength, high oxidation resistance, high quality carbon structural steel, alloy structural steel and stainless steel seamless steel pipe used for making steam boiler pipe of high pressure and above, and has good structure stability, hydraulic prop pipe.
