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.
