ASTM A240 F904L, UNS N08904, AWWA C207 Stainless Steel Slip On Flange, Flat Face
ASTM A240 F904L Stainless Steel Flanges are made up of a non-stabilized austenitic stainless steel material. The material has 23% nickel, 19% chromium and carbon, silicon, cupper, sulfur, manganese, phosphorus and 4% molybdenum in the composition. The flanges come under ASTM A182 and ASTM A240 specifications. The ASTM A240 F904L Stainless Steel Flanges has high corrosion resistant. They are in particular resistance to chloride ion, mild acids and oxidation. Thus, these flanges can be used in sour water, sea water and marine applications. Our Group manufactures and supplies various kinds of stainless steel falnges for more than 30 yesrs, like weld neck flanges, slip on flanges, blind flanges, orifice flanges, lap joint flanges, and so on. You can rest assured about our quality and service.
