Harsh Metalloys is a renowned manufacturer and supplier of Stainless Steel 316L Stud Bolts based in Mumbai, India. These stud bolts are fabricated from low-carbon austenitic stainless steel, offering superior corrosion resistance, especially in chloride-rich environments. Known for their excellent strength, weldability, and formability, 316L stud bolts are ideal for applications where resistance to harsh chemicals, acids, and marine conditions is critical. We supply these fasteners in various sizes, lengths, and threading options to meet global standards like ASTM A193. Our products are trusted in industries such as oil & gas, petrochemical, marine, and pharmaceuticals.
Stainless Steel 316L Stud Bolts consist of 16–18% chromium, 10–14% nickel, 2–3% molybdenum, and a maximum of 0.03% carbon, which enhances corrosion resistance and minimizes carbide precipitation. These bolts deliver a tensile strength of around 485 MPa and yield strength of 170 MPa. The molybdenum content improves pitting and crevice corrosion resistance, especially in marine and acidic environments. 316L offers excellent mechanical strength, toughness, and durability across a wide temperature range, making it suitable for both cryogenic and elevated-temperature service.
