AL6XN Overview
AL6XN is a superaustenitic stainless steel with outstanding resistance to chloride pitting， crevice corrosion and stress corrosion cracking. AL6XN is a that was developed for and is used in highly aggressive environments. It has high nickel (24%)， molybdenum (6.3%)， nitrogen and chromium contents that give it excellent resistance to chloride stress corrosion cracking， chloride pitting， and exceptional general corrosion resistance. AL6XN is primarily used for its improved pitting and crevice corrosion resistance in chlorides. It is a formable and weldable stainless steel.
Because of its nitrogen content， AL6XN has greater tensile strength than common austentitic stainlesses， while retaining high ductility and impact strength.
耐腐蚀性
铬、钼、镍和氮都有助于全面抵御各种介质的腐蚀。铬是在中性或氧化环境中赋予抗腐蚀性的主要成分。铬、钼和氮可增强抗点蚀能力。镍赋予奥氏体结构。在还原环境中，镍和钼都能提高抗氯化物应力腐蚀开裂的能力。
