Steel mills: Haynes; SMC; ATI; VDM; Outokumpu; NYK; Jinri Teikei, Fushun / Northeast Special Steel
GH4500 is a nickel-chromium-cobalt-based precipitation-hardening deformation high-temperature alloy with excellent high-temperature properties and comprehensive performance. Here are its core performance characteristics:
Physical properties
‌Melting point‌: approximately 1288 - 1343℃
‌Density‌: 8.05 - 8.7 g/cm³
‌Thermal conductivity‌: 10.9 - 15 W/(m·K)
‌Linear expansion coefficient‌: 12 - 14 × 10⁻⁶/℃ (25 - 800℃) Mechanical properties
Tensile strength: 1050 - 1200 MPa
Yield strength: 550 - 700 MPa
Elongation: 20 - 30%
Maintains anti-rheological properties at high temperatures (e.g., 950°C), with a steady-state creep rate lower than 5 × 10⁻¹⁰ s⁻¹
High-temperature performance
Temperature range: Long-term use ≤ 870°C, short-term up to 980°C
Antioxidation: Forms a dense Cr₂O₃ oxide film at high temperatures, effectively resisting oxidation and sulfidation corrosion
Creep resistance: At 950°C / 150 MPa conditions, the creep rate is lower than 5 × 10⁻¹⁰ s⁻¹
Corrosion resistance
Resistant to corrosion by acids, alkalis, salts, etc.
Suitable for complex environments such as oxidation, sulfidation, and reduction
Application fields
Mainly used for components such as aircraft engine blades, turbine discs, combustion chambers, etc., as well as key components of high-temperature equipment such as nuclear reactors and gas turbines.

Product parameter

Chemical composition
The chemical composition of GH4500 superalloy (in accordance with the actual production standard GB/T14992) is as follows:
‌Nickel (Ni): 72%-76% by weight ‌
‌Chromium (Cr): 18%-20% ‌
‌Cobalt (Co): 15%-20% ‌
‌Molybdenum (Mo): 3%-5% ‌
‌Carbon (C): ≤0.12% ‌
‌Iron (Fe): ≤4% ‌
‌Aluminum (Al): 2.75%-3.25% ‌
‌Titanium (Ti): 2.2%-2.6% ‌
‌Tungsten (W): 4%-5% ‌
‌Boron (B): 0.003%-0.008% ‌
The contents of other elements such as silicon (Si), manganese (Mn), phosphorus (P), and sulfur (S) are relatively low. Specific values can be referred to the standard GB/T14992.
