At Hazlewood Fasteners, we specialize in manufacturing and supplying premium-grade Stainless Steel 253 MA Bolts in Canberra, Australia, designed to perform exceptionally well under extreme heat and corrosive conditions. Engineered from high-temperature austenitic stainless steel, these bolts deliver a perfect balance of strength, oxidation resistance, and structural stability. Known for their excellent performance up to 1150°C, our 253 MA Bolts are trusted in industries that demand durability and dependability under thermal stress. Whether used in furnaces, refineries, or chemical plants, Hazlewood Fasteners ensures every bolt exceeds expectations in quality and reliability.
Stainless Steel 253 MA Bolts are composed of 20–22% chromium, 10–12% nickel, 0.05–0.10% nitrogen, and trace amounts of silicon, cerium, and rare earth metals. This precise combination enhances oxidation resistance, creep strength, and structural integrity at elevated temperatures. With a tensile strength of around 600 MPa and yield strength near 310 MPa, these bolts maintain superior mechanical performance under thermal cycling. The nitrogen content strengthens the austenitic structure, while rare earth elements improve the protective oxide layer, ensuring long-term stability and durability in high-temperature applications.
