W.Nr 2.4654 age hardenable nickel alloy very good strength up to 980°C
W.Nr 2.4654 is an age hardening austenitic (face-centred cubic) nickel-based superalloy. W.Nr 2.4654 is typically used in high temperature applications, particularly in gas turbines.
Formerly Grade 685
W.Nr 2.4654 is an age-hardenable, nickel-based superalloy with excellent strength properties through temperatures of roughly 980°C (1800°F). Other characteristics of Waspaloy include good corrosion resistance, as well as being relatively impervious to oxidation making it well suited for service in extreme environments.
W.Nr 2.4654 has useful strength at temperatures up to 760-870°C (1400-1600°F), and good oxidation resistance in gas turbine engine atmospheres up to 870°C (1600°F). The creep rupture strength of W.Nr 2.4654 is superior to that of Alloy 718 at temperatures above 620-650°C (1150-1200°F). Short time hot tensile strength is inferior to RA718 at temperatures up to 730°C (1350°F).

Excellent high-temperature strength and good resistance to oxidation at a temperature up to 1800° F. This superalloy has higher stability and strength ranges than those available for alloy 718.
W.Nr 2.4654 is used for gas turbine engine components that call for considerable strength and corrosion resistance at high operating temperatures. Current and potential applications include compressor and rotor discs, shafts, spacers, seals, rings and casings, fasteners and other miscellaneous engine hardware, airframe assemblies and missile systems
