Product Description
904L stainless steel
904L super austenitic stainless steel is a low carbon, high nickel, molybdenum austenitic stainless acid resistant steel, for the introduction of France's H • S company's proprietary materials. Has the very good activation - passive transition ability, excellent corrosion resistance, non oxidizing acid such as sulfuric acid has good corrosion resistance, acetic acid, formic acid, phosphoric acid, has good resistance to pitting corrosion of chlorine ions in the neutral medium, but also has good resistance to crevice corrosion and stress corrosion resistance. The utility model is suitable for sulfuric acid with various concentrations below 70 DEG C, and has good corrosion resistance at the atmospheric pressure of acetic acid and mixed acid of formic acid and acetic acid at any temperature and any temperature, and has good corrosion resistance.
