Aditya Stainless stands out as a leading manufacturer and supplier of Stainless Steel 317 Fasteners in Kolkata, India. They’re well-regarded for their corrosion-resistant and high-performance fastening solutions. SS 317 is an austenitic stainless steel alloy that’s enriched with molybdenum, giving it superior resistance to sulfurous, acetic, formic, and tartaric acids compared to SS 316. These fasteners are perfect for harsh environments and are crafted to meet global standards like ASTM A193/A194, DIN, and ASME specifications. Aditya Stainless offers a range of 317 fasteners—nuts, bolts, screws, studs, and washers—ensuring reliability in the chemical processing and marine industries.
Stainless Steel 317 Fasteners are made up of 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, along with controlled amounts of manganese, silicon, and carbon. These components boost the material’s corrosion resistance and mechanical strength. The fasteners boast a minimum tensile strength of 515 MPa, a yield strength of 205 MPa, and an elongation of 35%, which guarantees strength, flexibility, and long-lasting durability. SS 317 excels in both oxidizing and reducing environments, resisting pitting and crevice corrosion in aggressive chemicals, particularly those with chlorides, making it a dependable choice for structural and load-bearing applications.
