Stainless Steel 316H Bolts are top-notch fasteners crafted for situations where outstanding corrosion resistance, impressive strength, and durability are a must, especially in industrial and marine settings. Made from a high-carbon version of the 316 grade, these bolts offer enhanced mechanical strength even at high temperatures, all while keeping the remarkable resistance to pitting and crevice corrosion that comes with molybdenum-rich austenitic stainless steel. You’ll find Stainless Steel 316H Bolts to be perfect for chemical processing, petrochemical facilities, marine structures, and high-temperature equipment, ensuring they hold up reliably in tough environmental and operational conditions.
These bolts are made up of chromium (16–18%), nickel (10–14%), molybdenum (2–3%), and a higher carbon content than standard 316, which boosts their tensile and yield strength at elevated temperatures. Typically, they show a tensile strength ranging from 515 to 690 MPa and a yield strength of about 205 MPa, along with excellent creep resistance and ductility. The increased carbon content guarantees stability when things heat up, while the molybdenum enhances their resistance to corrosion in environments rich in chlorides and chemicals.
