Product information

Grade: GH4163
Steel Manufacturer: Haynes; SMC; ATI; VDM; Outokumpu; NYK; Jinri Railway, Fushun / Northeast Special Steel
GH4163 (a nickel-chromium-cobalt based precipitation hardening alloy) is a high-temperature alloy specially designed for the structural components of aircraft engine combustion chambers and thrust chambers. It possesses excellent high-temperature properties and mechanical properties.
High-temperature properties
It can be used for a long time at temperatures below 850°C, maintaining high yield strength (780 MPa level) and low creep rate (0.02%/h) below 800°C, with outstanding oxidation resistance, and no shedding after 1000 cycles of oxidation at 900°C. Mechanical properties
‌Strength‌: Tensile strength at room temperature: 850 - 1050 MPa, yield strength: 760 MPa;
‌Ductility‌: Extension rate: 15%, hardness: 320 HB;
‌Fatigue performance‌: Strong against cold and hot fatigue. No cracks after 5000 cycles of −40℃ ↔ 800℃. Stability
After being exposed at 800℃ for 5000 hours, the coarse-graining rate of the γ' phase was only 20%, which was significantly better than that of similar alloys. 
Processing performance
Weldability: TIG welding can be used, and the tensile strength of the joint reaches 90% of the base material;
Formability: It can be cold rolled into a 0.6mm thin sheet and formed into a 1.8D round cup with one deep drawing.
