ASTM A182 F304 Stainless Steel Flange
GNEE is an ISO 9001:2008 certified company that uses high-quality raw materials to manufacture stainless steel 304 flanges according to customer requirements, ensuring that all products have the due corrosion resistance.
ASTM A182 Stainless Steel 304 flanges are made from chromium-nickel austenitic stainless steel which contains between 15% and 20% chromium, while the alloy used to make these flanges contains 10.5% nickel. Such a chemical composition allows the ASTM A182 F304 flange to be easily cleaned with detergents during use and will not wear out during cleaning due to its good wear resistance and corrosion resistance.
ASTM A182 304 chromium-nickel austenitic stainless steel flange specifications also include weld neck, socket weld, slip through weld, lap joint and other types of flanges. Among them, ASTM A182 304 SS blind flange is used in power generation, boiler, water supply and other industries to prevent the flow of media or seal valves.
