Alpha Overseas trades SS 317L Fasteners, which is non-magnetic in the annealed condition but may become slightly magnetic after welding. Machining Alloy 317L Fasteners requires low speeds and constant feeds to reduce its tendency to work harden. Grade 317L Fasteners has excellent corrosion resistance in a wide range of chemicals, especially in acidic chloride environments such as those encountered in pulp and paper mills. Type 317L Fasteners should be heated to 1900 Degree F minimum and water quenched or rapidly cooled by other means. AISI 317L Fasteners is a low carbon or "L" grade which provides resistance to sensitization during welding and other thermal processes. 317L Stainless Steel Fasteners is often used in petrochemical and chemical process equipment, along with in pulp and paper manufacturing. Typical applications of Stainless Steel 317L Nuts include stainless steel piping and vessels in oil and gas industry, chemical plants and refineries. Stainless Steel 317L Bolts has approximately 1 % more chromium, nickel and molybdenum when compared with austenitic steel AISI 316L.

Through the controlled addition of nitrogen it is common for Stainless Steel 317L Washers to meet the mechanical properties of 317 straight grade, while maintaining a low carbon content. Stainless Steel 317L Screws is a molybdenum bearing austenitic chromium nickel steel similar to type 316, except the alloy content in this steel is somewhat higher.

Molybdenum content of Stainless Steel 317L Stud Bolts increases to 3 to 4 % from the 2 to 3 % found in 316 and 316L.
