Alloy Al6XN - UNS N08367 nickel-molybdenum alloy

The lowest carbon, high purity, nitrogen-bearing "super-austenitic" stainless alloy is called AL- 6XN®( UNS N08367). It has since been established that the AL- 6XN alloy is resistant to a wide variety of extremely corrosive environments, despite being intended to be seawater resistant. The AL6XN alloy is a more economical option to more expensive nickel-base alloys credited to its high strength and corrosion resistance, which makes this superior to conventional duplex metal steels.

Nickel-molybdenum alloy UNS N08367, also known as AL- 6XN® alloy, has excellent resistance to chloride pitting and crevice corrode. High ductility and impact power are still present in AUNS N08367. UNS N08367 has recently been used for seawater heat exchangers, chemical process tanks and sewerlines, offshore oil and gas creation equipment, seawater heat exchangers.
