Nickel Waspaloy AMS 5706

AMS 5706 is a specification of Nickel Waspaloy, a nickel-base age-hardenable superalloy with excellent high-temperature strength and good corrosion resistance by combustion products.

This specification is available in the form of forgings, bars and rings that are used for fasteners, flanges and rings that have a need for high strength at temperatures up to 1500°F (816°C). The AMS 5706 specification can also be used for oxidation resistance of up to 1750°F (954°C), and for other applications that require high strength and corrosion resistance.  The heat treatment is as follows:

  • Solution treatment – melt using consumable electrode or vacuum induction at 1825-1895°F (995-1035°C), and then oil quench for 4 hours;
  • Stabilization – reheat to 1550°F (845°C), and air cool for 4 hours;
  • Age harden – reheat to 1400°F (760°C), and air cool for 16 hours to produce hardness of 33-44 Rockwell C.

Please note that scale may be formed on the alloy during heat treatment in oxidizing atmospheres. However, this doesn’t affect the properties of the alloy and can be removed by acid pickling or mechanically.

AMS 5706 can be readily welded only in carefully controlled circumstances, using argon-arc methods and the Waspaloy AMS 5828 filler metal. Welds should be avoided in high-stress environments.

Hot working of AMS 5706 is done at 2140-1800°F (1170-980°C), while hydroforming, drawing, spinning, bending, and rolling can be used for cold working.
