Austenitic 904L Vapor Liquid Separator Stainless Demister Mist Elimiantor
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 and acid resistant steel. It is a proprietary material of H.S company of France. It has good activation passivation transformation ability, excellent corrosion resistance, good corrosion resistance in non oxidizing acids such as sulfuric acid, acetic acid, formic acid, phosphoric acid, good pitting resistance in neutral chloride ion medium, good crack corrosion resistance and stress corrosion resistance. It is suitable for sulfuric acid of various concentrations below 70 ºC, and it can resist any concentration and temperature of acetic acid under normal pressure, and the corrosion resistance of the mixed acid of formic acid and acetic acid is also very good.
