Stainless Steel 317L fasteners are primarily made up of iron, chromium (18–20%), nickel (11–15%), and molybdenum (3–4%), featuring low carbon content to boost corrosion resistance. This austenitic alloy showcases impressive mechanical properties, such as high tensile strength, toughness, and resistance to pitting and stress corrosion cracking. The low carbon content ensures stability during welding and when exposed to high temperatures, while also preserving dimensional integrity and surface finish. These traits make 317L fasteners perfect for applications that demand both mechanical strength and long-lasting resistance to harsh chemical and marine environments.
