GH4413, also known by its UNS designation H41990, is a premium nickel-based superalloy rod engineered to perform exceptionally in extreme high-temperature and corrosive environments. This alloy is widely recognized for its superior mechanical strength, excellent oxidation resistance, and remarkable thermal stability at temperatures up to 950°C (1742°F). The combination of these properties makes GH4413 rods highly suitable for critical components in aerospace, power generation, petrochemical, and metallurgical industries where reliability under stress and heat is mandatory.
High-Temperature Strength and Stability: GH4413 alloy maintains its structural integrity and mechanical properties under prolonged exposure to temperatures near 950°C, resisting deformation and creep effectively.
Oxidation and Corrosion Resistance: A well-balanced chromium content ensures excellent resistance to oxidation and corrosion, especially in environments with oxidizing gases and thermal cycling.
Excellent Fabrication Properties: Despite its high strength, GH4413 exhibits good hot-working, machining, and welding characteristics, allowing it to be manufactured into complex shapes and critical parts.
Thermal Fatigue Resistance: The alloy withstands repeated thermal cycling without significant cracking or microstructural degradation, essential for gas turbine and furnace applications.
Long Service Life: Components made from GH4413 provide extended operational life, reducing downtime and maintenance costs in demanding industrial settings.
