- AL-6XN
The AL-6XN
alloy is a superaustenitic stainless steel which was developed by [http://www.alleghenyludlum.com/ Allegheny Ludlum Corporation] . It exhibits far greater resistance to chloridepitting , crevicecorrosion and stress-corrosion cracking than exhibited by the standard 300 seriesstainless steel s, and is less costly than the traditional nickel-base corrosion resistant alloys.The UNS Designation of the AL-6XN alloy is N08367.
The high
nickel (24%) andmolybdenum (6.3%) contents of the AL-6XN alloy give it good resistance to chloride stress-corrosion cracking. The molybdenum confers resistance to chloride pitting. Thenitrogen content of AL-6XN alloy serves to further increase pitting resistance and also gives it higher strength than typical 300 series austenitic stainless steels, and thereby often allows it to be used in thinner sections. The high levels ofchromium , molybdenum and nitrogen in AL-6XN alloy all serve to produce exceptional corrosion resistance for this formable and weldable stainless steel.
