ASTM A376 TP347H Stainless Steel Seamless Pipe for High-temperature Central-station Service
Alloy 347 stainless steel are austenitic stainless steels that contain stabilizing elements. This alloys is easily welded. Annealing may not be required after welding unless stress relief is desired. 347 stainless steel has excellent resistance to oxidation and corrosion. With high creep strength, 347 stainless steel work best up to 1600 °F.
