Andre Stainless is a leading manufacturer and supplier of Stainless Steel 304H Bolts in Pulau Ujong, Singapore. SS 304H bolts are made for high-temperature strength and long-term use in heat-intensive environments. With a higher carbon content than SS 304, these bolts provide better creep resistance and tensile strength at high temperatures. Our 304H bolts come in various sizes and threading standards, suitable for thermal processing, pressure vessels, and boiler applications. Andre Stainless guarantees precise engineering, durability, and adherence to ASTM standards for fasteners used in high-stress, high-temperature operations across industrial sectors in Singapore.
Stainless Steel 304H contains 18–20% chromium, 8–10.5% nickel, and a higher carbon content (0.04–0.10%) compared to standard 304. It offers increased tensile strength (up to 750 MPa) and better creep resistance for high-temperature service above 500°C. SS 304H bolts maintain corrosion resistance, weldability, and mechanical stability during prolonged thermal exposure. They are non-magnetic in the annealed condition and have strong resistance to oxidation and scaling. These properties make SS 304H ideal for applications involving heat cycles, pressure loads, and chemical exposure.
