Applications of ASTM A376/A376M Austenitic Seamless Steel Pipes for Use at High Temperatures

Austenitic stainless steel pipe refers to stainless steel with austenitic structure at high temperature and room temperature. When the steel contains about 18% Cr, 8%~10% Ni, and about 0.1% C, it has a stable austenite structure.

Austenitic chromium nickel stainless steel includes the famous 18Cr-8Ni steel and the high Cr Ni series steel developed by increasing Cr and Ni content and adding elements such as Mo, Cu, Si, Nb, Ti, etc. on this basis. Austenitic stainless steel is non-magnetic and has high toughness and plasticity, but its strength is low. It is not possible to strengthen it through phase transformation, and can only be strengthened through cold working. For example, adding elements such as S, Ca, Se, Te, etc., will result in good machinability.
