AISI 904L 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 904L SS also known as SS 904L, AISI 904L, INOX 904L and SUS 904L comes with UNS N08904 and WNR 1.4539. Stainless Steel 904L 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 904L to be welded without sensitization to intergranular corrosion resulting from chromium carbide precipitation in the grain boundaries. SS 904L is non-magnetic in the annealed condition but may become slightly magnetic as a result of welding. 904L Stainless Steel cannot be hardened by heat treatment, however the material will harden due to cold working. 904L SS can be easily welded and processed by standard shop fabrication practices. The low carbon content of AISI 904L 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 904L can be dual certified as Type 317 with UNS S31700. The SUS904L provides improved resistance relative to 316L in strongly corrosive environments containing sulfurous media, chlorides, and other halides. SS 904L is widely used in Chemical and petrochemical process equipment, pulp and paper manufacturing and condensers in fossil and nuclear fueled power generation stations.
