Hazlewood Fasteners, based in Canberra, Australia, stands out as a top-notch manufacturer and supplier of high-quality industrial fasteners, celebrated for their strength, precision, and reliability. The company delivers fastening solutions that align with global engineering and quality standards, catering to various industries, including petrochemical, construction, power generation, and marine sectors. Among their impressive lineup, the Stainless Steel 304H Fasteners are particularly prized for their exceptional high-temperature strength, corrosion resistance, and durability. Crafted with care using cutting-edge production technology, these fasteners promise dependable performance, outstanding mechanical stability, and a long service life even in tough thermal and industrial environments.
Stainless Steel 304H Fasteners are made up of 18–20% chromium, 8–11% nickel, and a higher carbon content (0.04–0.10%) compared to standard 304 grades. This extra carbon boosts strength and creep resistance at high temperatures. These fasteners showcase remarkable tensile strength (up to 515 MPa) and yield strength around 205 MPa, along with excellent ductility and oxidation resistance. They maintain their structural integrity under thermal stress and offer great weldability and formability. SS 304H combines high mechanical strength with corrosion resistance, making it a perfect choice for high-temperature applications.
