Stainless Steel 317/317L Nuts are made with 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, which enhances their resistance to chemical corrosion and chloride attack. The 317L grade has a lower carbon content, improving weldability and reducing carbide precipitation. These nuts showcase impressive mechanical properties, including a tensile strength of around 515 MPa, yield strength close to 205 MPa, and an elongation of about 35%. They maintain toughness and ductility even at high temperatures, ensuring they perform reliably in harsh industrial, chemical, and marine settings where strength and corrosion resistance are essential.
