LORK is a special stainless steel manufacturer with 20 years of manufacturing experience.
317L (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, 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.
The low carbon content of 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 alloy can be dual certified as 317 (UNS S31700).
317L is non-magnetic in the annealed condition. It cannot be hardened by heat treatment, however the material will harden due to cold working. 317L can be easily welded and processed by standard shop fabrication practices.

317L can be easily welded and processed by standard shop fabrication practices.
The alloy is quite ductile and forms easily. The addition of molybdenum and nitrogen implies more powerful processing equipment may be necessary when compared with the standard 304/304L grades.
Working temperatures of 1652 - 2102°F (900 - 1150°C) are recommended for hot working processes. Do not work this alloy below 1742°F (950°C). If the final forming temperature falls below this threshold, a solution anneal of 1976 - 2156°F (1080 - 1180°C) is necessary. Rapid quenching is required.
The cold work hardening rate of 317L makes it less machinable than 410 stainless steel.
