Stainless steel 317 nuts are crafted from a blend of high chromium (18–20%), nickel (11–15%), and molybdenum (3–4%), which gives them exceptional corrosion resistance in harsh environments. This alloy boasts impressive mechanical properties, featuring a tensile strength of about 515 MPa, a yield strength of 205 MPa, and good elongation capabilities of roughly 35%. Thanks to their austenitic structure, these nuts maintain excellent toughness even in cryogenic conditions. The low carbon content in 317 stainless steel helps prevent intergranular corrosion, particularly after welding, making them ideal for high-stress and high-temperature fastening tasks.
