At Hazlewood Fasteners, we specialize in manufacturing and supplying Stainless Steel 422 Fasteners in Canberra, Australia—built to perform in high-temperature and high-stress environments. Known for their exceptional strength, wear resistance, and toughness, these fasteners are crafted from martensitic stainless steel, making them ideal for applications involving extreme heat and pressure. Stainless Steel 422 offers outstanding oxidation resistance and long-term dimensional stability. Whether used in turbines, power plants, or heavy machinery, our fasteners deliver superior reliability. At Hazlewood Fasteners, precision engineering and uncompromising quality come together to provide fastening solutions that last under the toughest industrial conditions.
Stainless Steel 422 Fasteners contain around 12% chromium, 0.2–0.3% carbon, and controlled amounts of molybdenum, tungsten, vanadium, and nickel. This martensitic stainless steel delivers high tensile strength (up to 760 MPa) and excellent hardness after heat treatment. It offers superior resistance to oxidation, scaling, and corrosion at temperatures up to 650°C. With excellent fatigue strength and creep resistance, 422 maintains stability under thermal cycling and stress. The alloy’s combination of hardness, toughness, and temperature endurance makes it a top choice for critical, high-performance fastening applications.
