Product information

Grade: GH5941
Steel Manufacturer: Haynes; SMC; ATI; VDM; Outokumpu; NYK; Jinri Tiefu, Fushun / Northeast Special Steel
GH5941 superalloy is a deformation-based superalloy with nickel as the matrix, featuring excellent high-temperature strength, oxidation resistance, and corrosion resistance. It is suitable for extreme high-temperature, high-pressure, and corrosive environments.
Chemical Composition
The chemical composition of GH5941 includes:
‌Nickel (Ni)‌: The matrix element, with a content of ≥50%, providing high-temperature stability
‌Chromium (Cr)‌: 15%-20%, forming a dense oxide film to enhance oxidation resistance
‌Molybdenum (Mo)‌: 5%-8%, enhancing high-temperature strength and creep resistance
‌Titanium (Ti)‌: 2%-3%, forming intermetallic compounds to strengthen high-temperature mechanical properties
‌Aluminum (Al)‌: 1.5%-2.5%, working with titanium to enhance high-temperature strength
‌Carbon (C)‌: ≤0.08%, controlling grain boundary precipitation
Mechanical Properties
At temperatures ranging from 800 to 1000°C, the tensile strength is ≥800 MPa, the yield strength is ≥600 MPa, and the elongation is ≥15%. The high-temperature endurance strength (1000 hours/850°C) is ≥200 MPa, and the creep resistance is superior to that of similar nickel-based alloys.
Oxidation and Corrosion Resistance
A dense Cr₂O₃ -Al₂O₃ composite oxide film forms on the surface, with an oxidation rate of ≤0.1g/(m²·h). It exhibits excellent sulfide corrosion resistance in fuel combustion environments containing sulfur.
Process Properties
‌Hot Working‌: Forging temperature 1100-1150°C, total deformation ≥50%
‌Cold Working‌: Allowable cold deformation ≥70%, surface roughness Ra ≤0.8 μm after annealing
‌Welding‌: Can be welded using argon arc welding, brazing, or resistance seam welding. Post-welding, a solution treatment is required

Product parameter

Chemical composition 
The chemical composition of GH5941 superalloy is as follows:
‌Carbon (C): 0.05 - 0.10%
‌Chromium (Cr): 19.0 - 23.0%
‌Nickel (Ni): 19.0 - 23.0%
‌Tungsten (W): 17.0 - 19.0%
‌Cobalt (Co): in excess
‌Manganese (Mn): 1.0 - 1.5%
‌Iron (Fe): ≤ 1.5%
‌Silicon (Si): ≤ 0.50%
‌Phosphorus (P): ≤ 0.02%
‌Sulfur (S): ≤ 0.01%
‌Copper (Cu): ≤ 0.50% Additional Explanation
Some sources indicate that there might be differences in components. For instance, the nickel content ranges from 38% to 46%, but the mainstream data is concentrated in the 19% to 23% range. This difference could be related to the alloy processing stage or the detection standards. It is recommended to rely on the detection data from authoritative institutions.
