904L High Temperature Resistant Stainless Steel Plate Manufacturers Wholesale GB 015cr21ni26mo5cu2 American Standard 904

904L ultra austenitic stainless steel is a low carbon, high nickel, molybdenum austenitic stainless steel, which is a special material introduced from H·S company in France. With good activation - passivation transformation ability, excellent performance, in the non-oxidizing acid such as sulfuric acid, acetic acid, formic acid, phosphoric acid has a good corrosion resistance, in the neutral containing chlorine ion medium has a good pitting resistance, and has good crack corrosion resistance and stress corrosion resistance. Suitable for various concentrations of sulfuric acid below 70℃, under atmospheric pressure resistance to any concentration, any temperature of acetic acid and formic acid and acetic acid in the mixed acid is also very good.

20Cr-24Ni-4.3Mo-1.5Cu grade and standard: UNS N08904, DIN1.4539, ASTM A240 (*** standard will be classified as stainless steel series, the original standard ASME SB-625 will be classified as nickel base alloy series), SUS890L.

904L is a complete austenitic structure. Compared with austenitic stainless steel with high molybdenum content, 904L is not sensitive to the precipitation of ferrite and α phase.

Density: 8.0g/cm3. Tensile strength: σb≥520Mpa. Elongation: δ≥35%
