The composition of Stainless Steel 317 Pipe Fittings includes chromium (18–20%), nickel (11–15%), and molybdenum (3–4%), which significantly boosts their corrosion resistance compared to 304 and 316 grades. They boast a tensile strength of about 515 MPa and a yield strength of roughly 205 MPa, along with good elongation and ductility. The addition of molybdenum enhances their resistance to pitting and crevice corrosion, while the low carbon content improves weldability and reduces carbide precipitation during fabrication.
