NCF 3015 alloy is a precipitation-hardenable, iron-nickel base alloy with mechanical properties between those of the iron-base and the more costly nickel-base alloys that have been used for engine valve applications. The alloy was designed for high strength and corrosion resistance up to 1400°F(760°C) and can also be considered as a replacement for nickel-base superalloys in applications involving the need for strength at elevated temperatures.
