Committed to customer satisfaction, timely delivery, and tailored solutions, Harshita Stainless caters to various sectors, including chemical processing, marine, petrochemical, and food industries, with precision-engineered products.
Stainless Steel 317L is a low-carbon, molybdenum-bearing austenitic stainless steel alloy that contains about 17–19% chromium, 11–15% nickel, 3–4% molybdenum, and ≤0.03% carbon to minimize carbide precipitation. It boasts excellent corrosion resistance, particularly against pitting and crevice corrosion in chloride environments. In terms of mechanical properties, 317L bolts have a tensile strength ranging from 485–620 MPa, a yield strength of around 205 MPa, and an elongation of 40–50%, with a hardness of about 70–85 HRB. The low carbon content enhances weldability without compromising strength, making these bolts perfect for welded structures in corrosive environments.
