904L (N08904, 1.4539) super austenitic stainless steel contains 14.0-18.0% chromium, 24.0-26.0% nickel and 4.5% molybdenum. 904L super austenitic stainless steel is a low carbon high nickel, molybdenum austenitic stainless acid resistant steel. It has very good activation-passivation transformation ability, excellent corrosion resistance, good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, phosphoric acid, and good corrosion resistance in neutral chloride ion-containing media. Excellent pitting corrosion resistance, good crevice corrosion resistance and stress corrosion resistance. It is suitable for sulfuric acid of various concentrations below 70�¯�¿�½?�?�°C, and has good corrosion resistance against acetic acid of any concentration and temperature under normal pressure, and the mixed acid of formic acid and acetic acid. Here are some of the most common international standards for 904L stainless steel: ASTM A240/A240M: Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications ASTM A276/A276M: Standard Specification for Stainless Steel Bars and Shapes ASTM A312/A312M: Standard Specification for Seamless, Welded, and Heavily Cold Worked Austenitic Stainless Steel Pipes ASTM B625/B625M: Standard Specification for UNS N08925, UNS N08031, UNS N08034, UNS N08932, UNS N08926, UNS N08354, UNS N08830, and UNS R20033 Plate, Sheet, and Strip EN 1.4539: European standard for austenitic stainless steel with high molybdenum content EN 10028-7: Flat products made of steels for pressure purposes - Part 7: Stainless steels EN 10216-5: Seamless steel tubes for pressure purposes - Technical delivery conditions - Part 5: Stainless steel tubes EN 10217-7: Welded steel tubes for pressure purposes - Technical delivery conditions - Part 7: Stainless steel tubes JIS G4304: Hot-rolled stainless steel plate, sheet and strip JIS G4305: Cold-rolled stainless steel plate, sheet and strip JIS G4312: Heat-resisting steel plate, sheet and strip GB/T 3280: Cold rolled stainless steel plate, sheet and strip GB/T 4237: Hot rolled stainless steel plate, sheet and strip GB/T 24511: Stainless steel and heat-resisting steel plate, sheet and strip for pressure equipments We can provide the following form:904L stainless steel coil; 904L stainless stee strip;904L stainless stee plate; 904L stainless steel sheets; 904L stainless steel tubes; 904L stainless steel pipe;904L stainless steel flat; 904L stainless steel bar
