A stable austenite contains about 18% Cr, 8%-10% Ni and about 0.1% C. Cr-Ni austenitic stainless steel includes the most familiar stainless steel 18Cr-8Ni and the series of high Cr-Ni steel developed by increasing Cr and Ni content and adding elements such as Mo, Cu, Si, Nb, Ti, etc. Austenitic stainless steel is characterized by non-magnetic, high plasticity and ductility but lower strength. It can be only strengthened via cold working (by adding S, Ca, Se, Te and etc., austenitic stainless steel can have excellent machinability).
A wide range of grades of alloy pipe is covered. And not limited in the following grades listed.
