Alloy AL6XN - UNS N08367 Bar

Alloy Al6XN® - UNS N08367 Bar commonly referred to as AL-6XN® alloy is a nickel-molybdenum alloy with excellent resistance to chloride pitting and crevice corrosion.

AUNS N08367 Bar retains high ductility and impact strength. UNS N08367 has been used for seawater heat exchangers, chemical process tanks and pipelines, offshore oil and gas production equipment, seawater heat exchangers.

AL-6XN® alloy (UNS N08367) Bar is a low carbon, high purity, nitrogen-bearing "super-austenitic" stainless alloy. The AL-6XN alloy was designed to be a seawater resistant material and has since been demonstrated to be resistant to a broad range of very corrosive environments. The high strength and corrosion resistance of the AL6XN 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.

The levels of chromium, molybdenum and nitrogen in AL-6XN all serve to provide resistance to acidic oxidizing chloride solutions previously achieved only by the nickel base alloys. High nickel (24%) and molybdenum (6.3%) contents make AL-6XN a solution to chloride ion stress corrosion cracking. Because of its nitrogen content, AL-6XN has greater tensile strength than common austenitic stainlesses, while retaining high ductility and impact strength. The ASME allowable stresses for AL-6XN are up to 75% higher than for 316L stainless, and more than twice those for the copper-nickel alloys.
