    AL-6XN ( UNS N08367 )

    AL6XN (UNS N08367) is a super austenitic 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.

    AL6XN (UNS N08367) also commonly referred to as alloy AL6XN is a low carbon, high purity, nitrogen-bearing “super-austenitic” nickel-molybdenum alloy with excellent resistance to chloride pitting and crevice corrosion. Alloy AL6XN’s high strength and corrosion resistance makes it a better choice than the conventional duplex stainless steels and a cost effective alternative to more expensive nickel-base alloys where excellent formability, weldability, strength and corrosion resistance are essential.

    AL-6XN is an extremely strong nickel-molybdenum alloy that provides many beneficial features, some of which include:

    • Excellent resistance to pitting and crevice corrosion in chloride solutions

    • Practical immunity to stress corrosion cracking in NaCl environments

    • High strength and toughness

    • 50% stronger than stainless steel

    • ASME coverage up to 800° F

    • Easily welded
