Harsh Metalloys is a reputed manufacturer and supplier of Stainless Steel 316L Bolts in Mumbai, India, delivering high-quality fastening solutions for critical industrial applications. These bolts are crafted from low-carbon austenitic stainless steel, providing excellent corrosion resistance, especially in marine and chloride-rich environments. Available in various sizes, types, and thread patterns, our 316L bolts conform to international standards like ASTM F593 and DIN specifications. Ideal for use in food processing, chemical, and offshore industries, our bolts offer high strength, superior finish, and long-lasting durability. Harsh Metalloys ensures timely delivery and precision-engineered fasteners for demanding operational conditions.
Stainless Steel 316L Bolts are composed of chromium (16–18%), nickel (10–14%), molybdenum (2–3%), and a maximum of 0.03% carbon, enhancing corrosion resistance and weldability. These bolts exhibit a minimum tensile strength of 485 MPa and yield strength of 170 MPa. The inclusion of molybdenum improves resistance to pitting and crevice corrosion, making them suitable for harsh and corrosive environments. Their non-magnetic nature and excellent mechanical properties ensure reliability in a wide range of temperature and pressure conditions, making them ideal for use in critical fastening applications.
