ASTM A312 TP317, TP317L Stainless Steel Welded Pipe For Oil And Gas Plants
ASTM A312 TP317L Stainless Steel is a low carbon austenitic grade. The Stainless Steel TP317L Pipe consists of iron, chromium, nickel, molybdenum, manganese, silicon, phosphorous, carbon, and sulfur. Stainless Steel TP317L Pipe works well in water conditions due to the content of molybdenum. The lower carbon content makes them to be resistant to sensitization and gives them higher creep-rupture properties.
