PRODUCT PARAMETERS
Overview
Waspaloy (UNS N07001/W. Nr. 2.4654) is a nickelbase, age hardenable superalloy with excellent hightemperature strength and good corrosion resistance,notably to oxidation, at service temperatures up to 1200°F (650°C) for critical rotating applications, and up to 1600°F (870°C) for other, less demanding, applications.
The alloy’s high-temperature strength is derived from its solid solution strengthening elements, molybdenum, cobalt and chromium, and its agehardening elements, aluminum and titanium.

Physical Constants
Mechanical properties-Room Temperature
Corrosion Resistance
Waspaloy has excellent resistance to corrosion by combustion products, encountered in gas turbines and aircraft jet engines, at temperatures up to 1600°F. Intergranular oxidation occurs at temperatures above 1600°F.
Heat treatment
Waspaloy is heat treated in a three-step sequence encompassing solution treatment, stabilization and agehardening.
A. For optimum high-temperature creep and stress-rupture properties.
Solution treatment - heat at 1080°C (1975°F)/4h/AC to produce hardness of 20-25 Rockwell C.
Stabilization - reheat to 845°C (1550°F)/24h/AC.
Age harden - reheat to 760°C (1400°F)/16h/AC to produce hardness of 34-40 Rockwell C.
B. For optimum room- and high-temperature tensile properties.
Solution treatment - heat at 995-1035°C (1825-1895°F)/4h/oil quench.
Stabilization - reheat to 845°C (1550°F)/4h/AC.
Age harden - reheat to 760°C (1400°F)/16h/AC to produce hardness of 34-44 Rockwell C.
Scale formed during heat-treatment in oxidizing atmospheres may be removed by acid pickling or by mechanical means.
