2 EQUIVALENT DESIGNATION

UNS N07001, AISI NO.685, W.Nr. 2.4654, CarTech^® Waspaloy, Harnes^®Waspaloy, NI-P101HT

3 APPLICATION

Waspaloy 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.

The alloy has been used for gas turbine engine parts which require considerable strength and corrosion resistance at temperatures up to 1600°F (871°C).

4 CHEMICAL COMPOSITION (wt%):

5 PHYSICAL CONSTANTS

Density: 8.19 g/cm³ (0.296 lb/in³)

Melting range: 1330-1360°C (2425-2475°F)

6 MECHANICAL PROPERTY

Typical mechanical properties (Heat treatment A)

7 CORROSION RESISTANCE
Waspaloy displays excellent resistance to corrosion by combustion products encountered in gas turbines and aircraft jet engines at temperatures up to 1600°F (871°C). Intergranular oxidation occurs at temperatures above 1600°F (871°C).

The alloy's oxidation resistance is good under conditions of frequent thermal cycling, and in continuous exposure to temperatures up to 1900°F (1038°C). It has performed well in atmospheres found in gas turbine engine service and in salt spray environments. Solution-treated material offers the best levels of corrosion resistance.

8 HEAT TREATMENT

Waspaloy is heat treated in a three-step sequence encompassing solution treatment, stabilization and age- hardening.

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.

9 WORKING INSTRUCTION

Hot working

Hot working is usually conducted in the temperature range 1800-2150°F (982-1177°C). This avoids rapid work hardening, possible cracking below 980°C (1800°F), and hot shortness above 1180°C (2150°F).

Cold working

The alloy may be cold worked by hydroforming, drawing, spinning, bending, roll forming, etc. It is considerably stronger than the AISI 300 series stainless steels at room temperature. Annealed alloy bar has also been successfully cold-headed into fastener configurations. Intermediate annealing is normally required because the alloy work hardens very rapidly.
