Waspaloy

Waspaloy is a registered trademark of United Technologies Corporation that refers to the hardening of austenitic ( face-centered cubic ) Ni-base superalloy. Waspaloy alloys are typically used in high temperature applications, especially gas turbines.

Composition

Nickel 58%, Chrome 19 %, 13% cobalt, molybdenum, 4%, 3% titanium, aluminum 1.4%

Properties

Waspaloy is a hardenable nickel-base superalloy having excellent strength properties at temperatures of about 980 ° C. Other features include good corrosion resistance, as well as a relative insensitivity to oxidation, thereby Waspaloy is well suited for use in extreme environments.

The alloy has a good strength at temperatures up to 760-870 ° C and a good oxidation resistance in gas turbine engines to 870 ° C. Creep rupture strength of Waspaloy is better than that of Inconel 718 at temperatures above 620-650 ° C. The short-term hot tensile strength at temperatures up to 730 ° C exceeds that of Inconel 718

Use

Waspaloy is often found in extreme environments. It is usual in gas turbines, seals, rings, shafts and turbine disks. The NIST - certified reference material 1243, a standard for X-ray fluorescence analysis is made ​​of Waspaloy.
