ASTM A312 TP317L Stainless Steel Tube For Chemical Petrochemical Processing
ASTM A312 TP317L Stainless Steel Tube For Chemical and Petrochemical Processing
Specifications
ASTM A312 TP317L (UNS S31703) is a molybdenum-bearing austenitic stainless steel with greatly increased resistance to chemical attack as compared to the conventional chromium-nickel austenitic stainless steels such as Alloy 304. In addition, Alloy 317L offers higher creep, stress-to-rupture, and tensile strength at elevated temperatures than conventional stainless steels. It is a low carbon or “L” grade which provides resistance to sensitization during welding and other thermal processes.
