Njabulo Stainless is a reputable manufacturer and supplier of Stainless Steel 316H Bolts, located in Cape Town, South Africa. These bolts are celebrated for their impressive high-temperature performance and outstanding corrosion resistance, making them perfect for demanding applications. Njabulo Stainless provides a range of bolt types, including hex bolts, stud bolts, U-bolts, and custom fasteners, all crafted to meet international standards. With a strong emphasis on durability and strength, the company caters to industries like petrochemical, power generation, marine, and construction, where dependable fastening in extreme conditions is crucial.
Stainless Steel 316H Bolts are made from an austenitic stainless steel alloy that contains 16–18% chromium, 10–14% nickel, and a higher carbon content (0.04–0.10%) compared to standard 316, which gives them enhanced strength at elevated temperatures. These bolts boast a tensile strength of around 515 MPa and a yield strength of 205 MPa, along with excellent ductility and toughness. The increased carbon content enhances creep resistance, making 316H bolts particularly suitable for high-temperature applications. They also offer good corrosion resistance in environments with chlorides and acids, ensuring they maintain structural integrity in both high-heat and corrosive settings.
