904L UNS N08904 1.4539 Reducing Forging Flange

904L UNS N08904 1.4539 Reducing Forging Flange
904L (N08904, 14539) Super austenitic stainless steel contains 14.0-18.0% chromium, 24.0-26.0% nickel, 4.5% molybdenum. 904L super austenitic stainless steel is a low carbon high nickel, molybdenum austenitic stainless acid steel, for the introduction of the French company's proprietary materials. Has good activation - passivation transition ability, excellent corrosion resistance, non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, phosphoric acid has a good corrosion resistance, in the neutral chloride ion medium has a good The anti-pitting corrosion resistance, at the same time has good resistance to crevice corrosion and stress corrosion resistance. Applicable to various concentrations below 70 ℃ sulfuric acid, at any pressure under any pressure, any temperature of acetic acid, and formic acid and acetic acid in the mixed acid corrosion resistance is also very good.
