Hex Forge Inc., a recognized manufacturer and supplier, manufactures and supplies ASTM A182 SS 304/304L RTJ Flange. We have satisfied the Flanges needs of many industrial clients with our high-quality products. These ASTM A182 SS 304 Flanges are austenitic stainless steel from the 300 Series. A minimum of 18% chromium and 8% nickel is paired with a maximum of 0.08 percent carbon in ASME SA182 304 Stainless Steel Flanges. All our goods are subjected to rigorous testing under all applicable national and international standards. When sending the materials, we provide all required documentation to the customers.

Carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, copper, and molybdenum are all present in Stainless Steel 304 RTJ Flange. With high operating temperatures, the material offers good strength and overall corrosion resistance. Metals like chromium and nickel are the principal non-iron or non-ferrous elements of the SS 304L RTJ Flange. Chromium-Nickel austenitic alloy is classified as UNS S30400 SS Flanges. The Stainless Steel 304 RTJ Flange is the same as the 304 RTJ Flange but has a 0.1 percent higher carbon content. In intermittent service to 1600°F and continuous service to 1690°F, 304L Stainless Steel RTJ Flange provides good oxidation resistance. The SS 304 RTJ Flange has a lot of positive qualities.
