347 Stainless Steel Tubes - Quick Section Links
347 Stainless Steel Tubes
347 stainless steel tubes are made of stainless steel and made to be used in applications that require the resistance to heat, corrosion and stability during continuous use. The grade has niobium which can reduce the formation of carbide after welding, and provides better resisting intergranular corrosion. These tubes are ideal for high-temperature process lines refining equipment, heat exchangers furnace components, boiler parts as well as chemical processing equipment. Their balanced composition ensures their performance in extreme environments in which regular stainless steel may not offer the same durability over time.
What are SUS 347 Tubes?
SUS 347 Tubes are niobium-stabilized austenitic stainless steel tube made for welding and use in high-temperature applications. They are also referred to by the names 347 stainless steel tubes UNS S34700 Tubes and DIN 1.4550 Tubes and SS 347 tubes in accordance with various standards. It is a good material for weld strength, oxidation resistance as well as protection from corrosion in intergranular areas. The selection should be based on pressure, temperature and wall thickness, as well as size and the conditions of service.
