These Stainless Steel 317/317L Washers are crafted from austenitic stainless steel alloys that boast a high molybdenum content (3–4%) along with enhanced levels of chromium and nickel. This unique composition provides significantly better corrosion resistance compared to 316 or 304, especially in acidic and chloride-rich environments. The Type 317L variant is the low-carbon option, which enhances weldability and resistance to intergranular corrosion. These washers deliver a tensile strength of about 515 MPa and a yield strength of around 205 MPa. Their impressive mechanical properties, paired with outstanding corrosion and oxidation resistance, make them perfect for high-stress and corrosive service conditions.
