AL6XN Overview

AL6XN is a superaustenitic stainless steel with outstanding resistance to chloride pitting, crevice corrosion and stress corrosion cracking. AL6XN is a 6 moly alloy that was developed for and is used in highly aggressive environments. It has high nickel (24%), molybdenum (6.3%), nitrogen and chromium contents that give it excellent resistance to chloride stress corrosion cracking, chloride pitting, and exceptional general corrosion resistance. AL6XN is primarily used for its improved pitting and crevice corrosion resistance in chlorides. It is a formable and weldable stainless steel.

Because of its nitrogen content, AL6XN has greater tensile strength than common austentitic stainlesses, while retaining high ductility and impact strength.

Corrosion Resistance

Chromium, molybdenum, nickel and nitrogen all contribute to overall resistance to corrosion by various media. Chromium is the principal agent for conferring corrosion resistance in neutral or oxidizing environments. Chromium, molybdenum and nitrogen increase resistance to pitting corrosion. Nickel imparts the austenitic structure. Nickel and molybdenum both provide increased resistance to chloride stress corrosion cracking in reducing environments.
