904L STAINLESS STEEL BAR

904L (N08904, 14539) 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, which is a proprietary material introduced from H.S. of France. It has good activation-passivation transformation ability and excellent corrosion resistance. It has good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, and phosphoric acid, and has good pitting resistance in neutral chloride ion media. It also has good resistance to crevice corrosion and stress corrosion. It is suitable for various concentrations of sulfuric acid below 70°C, and has good corrosion resistance in acetic acid of any concentration and any temperature under normal pressure, and mixed acid of formic acid and acetic acid.
