Stainless Steel 347 Flanges are adaptable components, perfect for extreme cold and heat conditions, with excellent resistance to rust and abrasion. These flanges are well-suited for use in boilers and robust exhaust systems, meeting stringent requirements outlined in ASTM A182 and A240 for high-pressure and high-temperature applications. They are in accordance with ANSI, ASME, BS, DIN, and EN regulations.
Stainless Steel 347 Flanges Overview: SS 347 Lap Joint Flanges are available in sizes ranging from ½ inches to 48 inches. Pressure ratings vary from classes 150 to 2500 and PN6 to PN64. Different face types include flat face, raised face, and ring type joint. The 347 Stainless Steel RTJ Flange is a ring type joint flange that requires welding onto pipe ends before connection. An alternative high carbon variation, 347H, offers increased toughness.
Stainless Steel 347 Flanges The Stainless Steel 347 Flanges are composed of 17% chromium, 9% nickel, and various other elements like carbon, manganese, silicon, phosphorus, sulfur, cobalt, and iron. With a high melting point of 1454 degrees Celsius, these flanges exhibit strength properties similar to the 304 grade. The minimum yield strength is 205MPa, and the minimum tensile strength is 515MPa. Different types of flanges are available to meet various application requirements, such as the SS UNS S34700 Weld Neck Flange, which has a welded neck for easy pipe connection. Piping Material is a reliable supplier and manufacturer of these flanges in different scales and grades. For more information on the products and pricing, please don't hesitate to reach out to us.
