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.

AL6XN® Superaustenitic Stainless Steel Features

alloy AL6XN 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

NO8367 Stainless Steel Alloy Applications
