Waspaloy® Bar - AMS 5706 - UNS N07001

AMS 5706 Waspaloy Material

Waspaloy® Bar - AMS 5706 is a precipitation hardening, austenitic nickel-based alloy which is used in elevated temperature applications. This alloy has been used for gas turbine engine parts, which require considerable strength and corrosion resistance at temperatures up to 1600ºF (871ºC). Major applications of Waspaloy® are for highly stressed parts in the turbine section of jet engines, such as blades, vanes, rings and discs.

Physical Properties

  • Density: 0.296 lb/in3, (8.19 g/cm3)

Non-magnetic

Maintains high strength, toughness, and excellent rupture properties to 1400ºF (760°C). This alloy has good resistance to oxidation and sulfidation to 1600ºF (871°C) due to its high chromium content. Waspaloy® Bar - AMS 5706 displays excellent resistance to corrosion by combustion products encountered in gas turbines and aircraft jet engines at temperatures up to 1600ºF (871ºC). Intergranular oxidation occurs at temperatures above 1600ºF (871ºC). This alloy has excellent resistance to stress corrosion cracking and adequate hot corrosion resistance.

Mechanical Properties

Waspaloy® AMS 5706 bar is difficult to machine, even in the solution treated condition. Rigid set-up, plenty of power, sharp tools and positive cuts are important. Use of carbide or ceramic tools is required.

Hardness

Hardness of stock is typically 230 BHN. Supplied in the solution treated condition - 1825-1900ºF (996-1038°C) for 1 hour. Waspaloy® Bar - AMS 5706 exhibits best machinability in this condition. After machining, parts are normally stabilized at 1550ºF (843°C) for 4 hours, air cooled, followed by precipitation aging at 1400ºF (760°C) for 16 hours, air cooled. The hardness of this alloy in the fully heat-treated condition ranges from 34 to 44 Rockwell C.

Machinability

Rating: 12% of B-1112

Typical stock removal rate: 30-50 surface feet/minute with carbide tooling.
