Waspaloy is a superalloy used in elevated temperature applications and is precipitation hardening, austenitic and nickel based. This grade has been used among others for gas turbine engine parts, requiring considerable strength up to 1200F (649C) and corrosion resistance at temperatures up to 1600F (871C).
Waspaloy is an age-hardenable nickel-based super alloy with excellent high temperature strength and good corrosion resistance at service temperatures up to 1200F (649C) for critical applications such as rotating components and up to 1600F (871C) for less demanding (stationary) applications.
This grades’ elevated temperature strength is derived from solid solution strengthening elements, molybdenum, cobalt and chromium & its age hardening elements like aluminum and titanium. Other characteristics of Waspaloy include excellent corrosion resistance, as well as being relatively impervious to oxidation making it well suited for service in extreme environments under elevated temperatures.
As such it has been widely used in gas turbine engine parts which require considerable strength and corrosion resistance. Waspaloy is typically manufactured by vacuum-induction plus consumable electrode remelting.
