904l stainless steel seamless pipe large diameter industrial pipe thick-walled tube n08904 corrosion resistant steel pipe

904L stainless steel seamless pipe, large-diameter industrial pipe, thick-walled pipe, N08904 corrosion-resistant steel pipe

904L (N08904, SMO24, 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 steel with excellent activation-passivation transformation ability and excellent corrosion resistance. It is suitable for use in non-oxidizing acids such as sulfuric acid.Acetic acidAcetic acid, phosphoric acid, and formic acid exhibit excellent corrosion resistance. They have good resistance to pitting corrosion in neutral media containing chloride ions. They also have good resistance to crevice corrosion and stress corrosion cracking. Suitable for a variety of concentrations of sulfuric acid at temperatures below 70°C, they are also resistant to any concentration and temperature of acetic acid under normal pressure. They also exhibit good corrosion resistance in mixtures of formic acid and acetic acid.
