706 is a precipitation-hardenable nickel-base alloy with high strength from cryogenic temperatures to about 1200°F (650°C). The alloy has similar characteristics to those of 718 but has improved fabricability and can be processed into larger ingots and forgings than other superalloys with excellent resistance to strain-age cracking of weldments. 706 is used for a variety of applications that require high elevated-temperature strength in larger section sizes along with good fabricability or where pitting and stress corrosion cracking are concerns.
turbine discs in large industrial gas turbines as well as aerospace turbines. Other turbine engine parts include shafts, cases, mounts, and fasteners: Non-magnetic oil drilling components, such as drill collars, stabilizers, and measuring/logging-while-drilling (MWD/LWD) housings
