Aditya Stainless stands out as a leading manufacturer and supplier of Stainless Steel 317L Bolts, proudly based in Kolkata, India. These bolts are celebrated for their exceptional corrosion resistance, especially in tough environments filled with harsh chemicals, acids, and chlorides. The SS 317L variant is a low-carbon version of 317, which not only offers great weldability but also reduces the chances of intergranular corrosion. Our product lineup features hex bolts, stud bolts, anchor bolts, and U-bolts, all crafted in accordance with ASTM A193 and other global standards. These bolts are widely utilized in industries like chemical processing, marine, pulp and paper, and pharmaceuticals, providing durable and dependable fastening solutions.
Stainless Steel 317L Bolts are composed of about 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, with a maximum carbon content of just 0.03%. The molybdenum content significantly boosts resistance to pitting and crevice corrosion in environments rich in chlorides. These bolts boast a minimum tensile strength of 515 MPa, a yield strength of 205 MPa, and an elongation of 35%. Known for their excellent formability, weldability, and high-temperature strength, SS 317L bolts are a trustworthy choice for demanding applications that require both mechanical durability and chemical resistance.
