Hazlewood Fasteners, located in Canberra, Australia, is a reliable manufacturer and supplier of top-notch Stainless Steel 321 / 321H Nuts, crafted for outstanding performance in high-temperature and corrosive settings. These titanium-stabilized stainless steel nuts are built to withstand intergranular corrosion and oxidation, even after prolonged exposure to high heat. Using cutting-edge technology and high-quality materials, SS 321 / 321H Nuts deliver remarkable strength, precision, and long-lasting reliability. They find their place in industries like chemical processing, power generation, marine, and aerospace, where durability, heat resistance, and mechanical integrity are crucial for trustworthy fastening solutions.
Stainless Steel 321 / 321H Nuts are made up of 17–19% chromium, 9–12% nickel, and a titanium stabilizer (at least five times the carbon content), which helps prevent carbide precipitation during welding and thermal exposure. The 321H grade, featuring a higher carbon content (0.04–0.10%), boosts creep strength and high-temperature mechanical properties. These nuts offer a tensile strength of 515–700 MPa, a yield strength of around 205 MPa, and excellent oxidation resistance up to 870°C. The blend of ductility, corrosion resistance, and structural stability guarantees optimal performance in environments with heat, pressure, and chemical exposure.
