    High-Temperature Alloy GH2903/GH903/N09903/Incoloy903 Bolt With Thermal Expansion Resistance For Aerospace Specifications


    The GH2903 (also known as GH903, N09903, or Incoloy 903) is a high-temperature, high-strength nickel-iron-cobalt alloy designed for extreme environments. It exhibits excellent mechanical properties, oxidation resistance, and stability under prolonged exposure to high temperatures. The alloy is precipitation-hardened with niobium and titanium, enhancing its strength and creep resistance.

    GH2903 bolts are widely used in aerospace, gas turbines, and high-performance engines due to their ability to withstand stress and thermal fatigue. They maintain structural integrity in temperatures up to 650°C (1202°F), making them ideal for critical applications. Their superior corrosion and oxidation resistance further ensure reliability in harsh conditions.

    These bolts undergo precision machining and heat treatment to optimize their mechanical properties. Their high tensile strength, fatigue resistance, and long service life make them indispensable in demanding engineering applications, where safety and durability are paramount.

    GH2903/GH903/N09903/Incoloy903 Alloy Bolt Key Features:

    The GH2903 (GH903, N09903, Incoloy 903) high-temperature alloy bolt is known for its excellent mechanical properties, corrosion resistance, and high-temperature stability. Here are its key features:

    1. High-Temperature Strength

    • Maintains excellent strength and structural stability at elevated temperatures (up to 650°C (1200°F)).
    • High creep and stress-rupture resistance.

    2. Excellent Fatigue Resistance

    • Designed to withstand cyclic loading and thermal fatigue, making it suitable for aerospace and turbine applications.

    3. Oxidation and Corrosion Resistance

    • Offers good oxidation resistance in high-temperature environments.
    • Resists corrosion in industrial and marine conditions.

    4. Precipitation Hardening for Strength

    • Strengthened through precipitation hardening with elements like titanium, niobium, and aluminum, which enhance creep and fatigue resistance.

    5. Low Thermal Expansion

    • Controlled expansion properties help reduce thermal distortion, making it suitable for precision components in gas turbines and aerospace applications.

    6. Good Weldability and Machinability

    • Can be welded using standard techniques, although post-weld heat treatment may be necessary.
    • Machinability is fair but requires specialized tooling due to its strength and toughness.
