AISI 317L Stainless Steel is a low carbon austenitic stainless steel with molybdenum, that provides improved corrosion resistance over 304L and 316L and resistance to sensitization during welding and other thermal processes.

AISI 317L SS also known as SS 317L, AISI 317L, INOX 317L and SUS 317L comes with UNS S31703 and WNR 1.4438. Stainless Steel 317L is a molybdenum bearing austenitic stainless steel intended to provide improved corrosion resistance relative to Type 304l and 316L in highly corrosive process environments, particularly those containing chlorides or other halides. The low carbon permits Type 317L to be welded without sensitization to intergranular corrosion resulting from chromium carbide precipitation in the grain boundaries. SS 317L is non-magnetic in the annealed condition but may become slightly magnetic as a result of welding. 317L Stainless Steel cannot be hardened by heat treatment, however the material will harden due to cold working. 317L SS can be easily welded and processed by standard shop fabrication practices. The low carbon content of AISI 317L enables it to be welded without intergranular corrosion resulting from chromium carbide precipitation enabling it to be used in the as-welded condition. With the addition of nitrogen as a strengthening agent, the Type 317L can be dual certified as Type 317 with UNS S31700. The SUS317L provides improved resistance relative to 316L in strongly corrosive environments containing sulfurous media, chlorides, and other halides. SS 317L is widely used in Chemical and petrochemical process equipment, pulp and paper manufacturing and condensers in fossil and nuclear fueled power generation stations.
