ASTM B462 UNS N08367 is a super austenitic stainless steel with excellent resistance to chloride pitting, crevice corrosion and stress corrosion cracking. N08367 is a 6-molybdenum alloy developed for and used in highly corrosive environments. Its high nickel (24%), molybdenum (6.3%), nitrogen and chromium contents give it excellent resistance to chloride stress corrosion cracking, chloride pitting and excellent general corrosion resistance. N08367 is mainly used to improve its resistance to pitting and crevice corrosion in chlorides. It is a formable and weldable stainless steel.
Corrosion Resistance
Chromium, molybdenum, nickel and nitrogen all contribute to overall resistance to corrosion by various media. Chromium is the primary agent for imparting corrosion resistance in neutral or oxidizing environments. Chromium, molybdenum and nitrogen increase resistance to pitting corrosion. Nickel imparts an austenitic structure. Both nickel and molybdenum provide higher resistance to chloride stress corrosion cracking in reducing environments.
