Stainless Steel 904L Flanges
Arrow Piping Solutions is a leading manufacturer and supplier of Stainless Steel 904L Flanges in India. We offer a comprehensive range of ASTM A182 SS 904L Pipe Flanges, including Lap Joint Flanges, SORF Flanges, Socket Weld Flanges, Threaded Flanges, Plate Flanges, and Spectacle Blind Flanges at competitive prices across the country.
SS 904L is a high-alloy austenitic stainless steel with added Molybdenum and Copper, making it highly resistant to crevice corrosion, pitting, and sulfuric acid. These properties make it suitable for harsh and corrosive environments such as chemical processing, pollution control, and marine applications. Its low carbon content also improves weldability and prevents intergranular corrosion during welding.
Arrow Piping Solutions manufactures SS 904L Flanges as per ASTM A182 standards, available in all pressure classes and face types. Our products are known for high strength, dimensional accuracy, and excellent surface finish, making them ideal for critical industries such as oil & gas, power generation, and pharmaceuticals.
