AL-6XN®       ESPECIFICAÇÕES TÉCNICAS

AL-6XN alloy is a super austenitic stainless steel with outstanding resistance to chloride pitting and crevice corrosion. AL-6XN alloy offers a means to upgrade corrosion resistance significantly from 316L stainless, but without the expense of using alloy C-276 and other high nickel alloys.
Because of its nitrogen content, AL-6XN alloy has greater tensile strength than common austenitic stainless, while retaining high ductility and impact strength. The ASME allowable stresses for AL-6XN alloy are up to 40% higher than for 316L stainless, and more than twice those for alloy 400 (Ni-Cu).
