ASTM A182 F347 Welding Neck Flange A182 F347 UNS S34700 Flange ASME B16.5
We are a professional flange manufacturer and export of ASTM A182 F347 FLANGES UNS S34700 Flange
ASTM A182 F347 is a stabilized, austenitic stainless steel alloy containing chromium and nickel, with the addition of columbium (niobium) for stabilization against carbide precipitation during welding. This alloy offers outstanding resistance to intergranular corrosion and oxidation, making it suitable for applications in harsh environments.
ASTM A182 standard which covers forged or rolled alloy and stainless steel pipe flanges, forged fittings, and valves designed for high-temperature service.
Grade F347: The “F” in F347 stands for “Forging Quality,” and “347” is the grade designation.ASTM A182 F347 is a stainless steel grade with specific chemical composition and mechanical properties. It is a stabilized austenitic stainless steel containing niobium, which provides enhanced resistance to intergranular corrosion.
