Aditya Stainless is a well-respected manufacturer and supplier of Stainless Steel 316H Fasteners, proudly based in Kolkata, India. We specialize in providing high-strength fastening solutions designed for tough, high-temperature, and corrosive environments. SS 316H is a high-carbon variant of 316 stainless steel, known for its superior strength and creep resistance when exposed to elevated temperatures. Our range of 316H fasteners includes various types such as bolts, nuts, screws, washers, studs, and threaded rods, all crafted to meet global standards like ASTM A193, A194, and ASTM F593. These fasteners find extensive use in industries like chemical, petrochemical, oil & gas, and marine.
Stainless Steel 316H Fasteners are composed of 16–18% chromium, 10–14% nickel, 2–3% molybdenum, and a higher carbon content (0.04–0.10%), which boosts their strength and hardness at high temperatures. They deliver a minimum tensile strength of 515 MPa and a yield strength of 205 MPa, along with excellent creep resistance in elevated temperatures. The addition of molybdenum enhances their resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Thanks to their impressive mechanical properties and corrosion resistance, 316H fasteners are reliable in both oxidizing and reducing environments, making them perfect for demanding industrial conditions.
