At Hazlewood Fasteners, we manufacture and supply top-quality Stainless Steel 253 MA Fasteners in Canberra, Australia—crafted to perform under the most demanding high-temperature and corrosive conditions. Known for their exceptional oxidation resistance, strength, and durability, these fasteners are engineered using advanced materials designed to withstand temperatures up to 1150°C. The 253 MA alloy combines the benefits of strength, ductility, and heat resistance, making it ideal for both industrial and thermal applications. Whether used in furnaces, refineries, or chemical plants, Hazlewood Fasteners’ 253 MA Fasteners deliver reliability, consistency, and long-lasting performance in every fastening application.
Stainless Steel 253 MA Fasteners are composed of 20–22% chromium, 10–12% nickel, 0.05–0.10% nitrogen, and small amounts of silicon, cerium, and rare earth elements that enhance oxidation and creep resistance. This alloy offers a tensile strength of around 600 MPa and yield strength near 310 MPa, maintaining stability under thermal stress. The addition of nitrogen improves structural integrity and toughness, while rare earth metals strengthen the protective oxide layer. These properties make 253 MA ideal for continuous service in high-temperature, oxidizing, and carburizing environments
