904L Stainless Steel Plate

904L stainless steel plate (N08904, 14539) contains 14.0-18.0% chromium, 24.0-26.0% nickel, and 4.5% molybdenum in super austenitic stainless steel.
904L super austenitic stainless steel plate is a low-carbon, high-nickel, molybdenum austenitic stainless acid-resistant steel. It has good pitting resistance in neutral chloride ion media, as well as good crevice corrosion resistance and stress corrosion resistance. 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.
