Super Austenitic Stainless Steels

Super austenitic stainless steels contain high levels of chromium and higher levels of nickel together with additions of molybdenum and nitrogen.  The result is a series of austenites, stronger than conventional 300 series stainless and with superior resistance to pitting, crevice corrosion, and stress corrosion cracking.
