Austenitic stainless steel pipe refers to stainless steel with austenitic structure at high temperature and normal temperature. When steel contains approximately 18% Cr, 8%~10% Ni, and approximately 0.1% C, it will have 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 the Cr and Ni content and adding Mo, Cu, Si, Nb, Ti and other elements. Austenitic stainless steel is non-magnetic and has high toughness and plasticity, but its strength is low. It cannot be strengthened through phase transformation. It can only be strengthened through cold working. If elements such as S, Ca, Se, Te, etc. are added, it has good Easy to cut.
