About AL-6XN®

AL-6XN® (UNS N08367) is a 6% molybdenum, low carbon, nitrogen-bearing super-austenitic stainless alloy. The alloy was originally designed for seawater applications. AL-6XN® has also been successfully used in a broad range of very corrosive environments including the rapidly developing biopharm markets.

The high strength and corrosion resistance of the AL-6XN® alloy make 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 the registered trademark of Allegheny Ludlum Corporation.
