CarTech 706 alloy 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 alloy 718 but has improved fabricability and can be processed into larger ingots and forgings than other superalloys. The alloy has excellent resistance to strain-age cracking of weldments.

Applications:
CarTech 706 alloy has been used for a variety of applications that require high elevated-temperature strength in larger section sizes along with good fabricability. The alloy has been used for turbine discs in large industrial gas turbines as well as aerospace turbines. Other turbine engine parts include shafts, cases, mounts, and fasteners.

The alloy is also a candidate for oil and gas industry applications because of its good combination of strength and corrosion resistance. Non-magnetic oil drilling components, such as drill collars, stabilizers, and measuring/logging-while-drilling (MWD/LWD) housings, are typically made using Cr-Mn-N austenitic stainless steels. In harsh drilling environments where pitting and stress corrosion cracking are concerns, CarTech 706 alloy has been shown to be superior in laboratory tests.
