Product information

Grade: GH5605
Steel Manufacturer: Haynes; SMC; ATI; VDM; Outokumpu; NYK; Jinri Railway, Fushun / Northeast Special Steel
GH5605 superalloy is a cobalt-based solid solution strengthened alloy with excellent high-temperature strength, oxidation resistance, and corrosion resistance. It is widely used in high-temperature components such as aircraft engines. ‌
Chemical Composition and Strengthening Mechanism
The alloy is based on cobalt (with the remainder), containing elements such as chromium (19-21%) and nickel (9-11%), and enhances high-temperature properties through solid solution strengthening. The carbon content is controlled at 0.05-0.15%, balancing strength and ductility. Trace amounts of silicon and manganese further optimize the stability of the microstructure and limit the formation of low-melting-point impurity phases. ‌
High-Temperature Mechanical Properties
‌Creep Resistance‌: At 700°C, the creep resistance strength ≥ 100 MPa/1000 hours, suitable for long-term high-temperature service. ‌
‌Elastic Modulus‌: At room temperature, it is 210 GPa, and at 650°C, it still maintains 181 GPa, showing excellent high-temperature rigidity. ‌
‌Tensile Strength‌: At room temperature, ≥ 1000 MPa, at 1000°C, ≥ 600 MPa.
Antioxidation and Corrosion Resistance
‌Antioxidation Layer‌: Forms a dense Cr₂O₃ film above 800°C, effectively blocking oxidation. ‌
‌Corrosion Resistance‌: Resistant to acid, alkali, and salt medium corrosion, suitable for harsh environments. ‌
Process Performance
‌Density‌: Approximately 9.13 g/cm³, balancing strength and weight. ‌
‌Melting Point‌: Approximately 1300°C, with strong high-temperature stability. ‌
‌Processing Characteristics‌: Good weldability and adaptability to heat treatment processes, and performance can be optimized through solid solution + aging treatment.

Product parameter

Chemical properties

‌Cobalt (Co): remainder (main component) ‌
‌Chromium (Cr): 19%-21% ‌
‌Carbon (C): 0.05%-0.15%
‌Silicon (Si): ≤0.4% ‌
‌Manganese (Mn): 1.0%-2.0% ‌
‌Phosphorus (P): ≤0.04% ‌
‌Sulfur (S): ≤0.03% ‌
‌Iron (Fe): ≤3.0% ‌
Special elements
‌Molybdenum (Mo): 3%-5% (part of the source mentions, not the standard range) ‌
‌Titanium (Ti), aluminum (Al), niobium (Nb): trace addition (about 0.5%-1%) ‌
Component characteristics
This alloy is based on cobalt, combined with Cr-Ni solid solution strengthening to form a dense oxide film, enhancing oxidation resistance and corrosion resistance. The low-carbon design (C ≤ 0.15%) balances strength and plasticity, while optimizing welding performance.
