These Stainless Steel 317/317L Bolts are made up of chromium (18–20%), nickel (11–15%), and molybdenum (3–4%), with the 317L variant featuring low carbon content for better weldability. They excel in resisting pitting, crevice, and general corrosion, particularly in acidic and chloride-rich settings. With a tensile strength ranging from 515–620 MPa and a yield strength of 205–240 MPa, they also boast good elongation properties, which contribute to their toughness and ductility. The low carbon version, 317L, helps reduce carbide precipitation, enhancing corrosion resistance during welding and exposure to high temperatures.
