At Hazlewood Fasteners, we are a trusted manufacturer and supplier of premium-quality Incoloy Bolts in Canberra, Australia. These bolts are engineered from high-performance nickel-iron-chromium alloys designed to resist oxidation, carburization, and corrosion in high-temperature environments. Incoloy Bolts deliver outstanding strength and stability even under extreme thermal and mechanical stress. Their exceptional resistance to acids, salts, and aggressive chemicals makes them an ideal choice for chemical processing, power generation, marine engineering, and oil & gas industries. With precision threading and durability, our Incoloy Bolts ensure long-lasting performance in demanding industrial environments.
Incoloy Bolts are composed primarily of nickel (30–46%), iron, and chromium, with small additions of titanium, aluminum, and molybdenum depending on the grade. This composition provides superior resistance to oxidation, scaling, and high-temperature corrosion. They exhibit tensile strength up to 760 MPa and yield strength around 345 MPa, maintaining structural integrity in temperatures exceeding 1000°C. These bolts offer excellent mechanical toughness, weldability, and resistance to stress cracking, making them suitable for extreme industrial conditions that require both chemical and thermal endurance.
