1. What is UNS N07718?

UNS N07718is a precipitation-hardenable nickel-based superalloy with high nickel (50.0-55.0%), chromium (17.0-21.0%), niobium (4.75-5.50%), and titanium (0.65-1.15%), offering outstanding strength, creep resistance, and corrosion resistance in high-temperature and corrosive environments. The alloy’s gamma-prime and gamma-double-prime strengthening phases make UNS N07718 alloy steel plate ideal for jet engine components, turbine disks, and oilfield equipment. Compared to UNS N06690, UNS N07718 provides superior mechanical strength but lower corrosion resistance in nuclear water environments.

Gangsteel’s UNS N07718 is tailored for high-performance applications, offering a robust alternative to nickel alloy steel grades like UNS N07750 and UNS N06022.
