Andre Stainless is a trusted name in the manufacturing and supply of Stainless Steel 442 Stud Bolts right in Pulau Ujong, Singapore. They’re well-known for crafting high-performance fasteners that excel in heat-resistant and structural applications. With a solid background in ferritic stainless steel products, Andre Stainless produces SS 442 stud bolts that offer outstanding oxidation resistance, thermal stability, and mechanical strength, even in high-temperature settings. These bolts are made using cutting-edge manufacturing techniques and rigorous quality controls to ensure they meet international standards, making them perfect for use in furnaces, exhaust systems, power generation units, and other industrial environments where heat and corrosion resistance are crucial.
Stainless Steel 442 Stud Bolts are crafted from a high-chromium ferritic stainless steel alloy that contains about 18–23% chromium. This unique blend gives them enhanced oxidation resistance and decent corrosion resistance, especially in oxidizing and thermal conditions. Typically, these bolts boast a tensile strength ranging from 450–600 MPa and show impressive resistance to scaling at temperatures reaching up to 1000°C. Thanks to their low thermal expansion and high thermal conductivity, SS 442 maintains dimensional stability and structural integrity, even when temperatures fluctuate.
