At Hazlewood Fasteners in Canberra, we craft fasteners that redefine endurance. Our stainless steel 347H fasteners are engineered for strength, stability, and performance in extreme heat and corrosive environments. With enhanced carbon content for superior creep strength, they stand firm where other materials weaken. Each fastener is precision-built to ensure secure, long-lasting connections across high-temperature assemblies and pressure systems. Resistant to oxidation and intergranular corrosion, Hazlewood Fasteners’ 347H fasteners embody reliability under fire—fasteners that hold their form, protect your structures, and deliver the kind of unwavering performance that only true engineering mastery can achieve.
Stainless steel 347H fasteners are composed of a niobium-stabilized austenitic alloy enriched with chromium and nickel. The added carbon increases creep and tensile strength, ensuring exceptional performance in continuous high-temperature service. These fasteners resist intergranular corrosion and oxidation up to 870°C while maintaining structural integrity under thermal stress. The niobium stabilization prevents carbide precipitation during welding, enhancing durability and longevity. With superior mechanical strength, thermal stability, and corrosion resistance, 347H fasteners deliver dependable performance in demanding industrial environments where heat and pressure are constants.
