Material summary and usage


904L steel is high nickel and molybdenum austenitic stainless acid resistant steel. As it contains high contents of chrome, molybdenum and copper, it has excellent activation and passivation ability, with low corrosion rate in the passivation area (because of high chrome). Meanwhile, it has good pitting corrosion and crevice corrosion resistant performance (because of high chrome and molybdenum) and good stress corrosion resistant performance (because of high nickel). It has good corrosion resistant in non-oxidizing acids such as sulfuric acid, formic acid and phosphoric, and has good pitting corrosion resistance in neutral solution containing chlorides.
