At Hazlewood Fasteners in Canberra, we design fasteners that push the limits of endurance. Our stainless steel 347H stud bolts are precision-engineered to perform in environments defined by heat, pressure, and corrosion. With enhanced carbon content for superior creep strength, these bolts maintain their integrity even under extreme thermal conditions. Stabilized with niobium, they resist intergranular corrosion and oxidation, ensuring unwavering reliability. Whether in refineries, power plants, or high-temperature assemblies, Hazlewood Fasteners’ 347H stud bolts embody strength that endures—holding every structure with the precision, stability, and resilience that define world-class engineering.
Stainless steel 347H stud bolts are forged from a niobium-stabilized, high-carbon austenitic alloy rich in chromium and nickel. The increased carbon enhances creep resistance and tensile strength at elevated temperatures, while niobium prevents carbide precipitation and intergranular corrosion. These bolts maintain excellent oxidation resistance up to 870°C, providing dimensional stability under prolonged heat exposure. With superior ductility, toughness, and weldability, 347H stud bolts deliver high-temperature reliability, structural strength, and long-lasting performance—engineered for demanding applications where heat, pressure, and precision intersect.

Stainless steel 347H stud bolts excel in high-temperature and high-stress environments where ordinary fasteners lose their strength. They are extensively used in petrochemical refineries, boiler systems, power generation plants, and heat exchangers. Their superior oxidation and creep resistance make them ideal for pressure vessels, furnace assemblies, and exhaust systems exposed to extreme thermal cycling. In marine, aerospace, and industrial fabrication, they ensure steadfast connections under heat and mechanical strain. Hazlewood Fasteners’ 347H stud bolts are the embodiment of engineered endurance—crafted to secure critical systems where reliability is not an option, but an expectation.
Our stainless steel 347H stud bolts in Hazlewood Fasteners go through careful quality testing to ensure exceptional performance. Our rigorous testing includes hardness testing, chemical analysis using spectroanalysis, PMI testing for inspection. Quality of materials, tensile strength analysis, micro-macrostructural analysis, and testing for high thermal resistance. And to ensure stability, each bolt lasts longer in extreme conditions, Meeting stringent industry standards for corrosion resistance and reliability, we carefully pack each stud bolt to ensure safe transport and come in condition optimized for immediate use in your critical applications to provide peace of mind and reliable performance.
