INCONEL 718 (UNS N07718) is a nickel-chromium alloy that offers exceptional strength and corrosion resistance at high temperatures, with an added benefit of excellent fatigue and thermal-fatigue strength. Its composition includes significant amounts of niobium and molybdenum, which help in the precipitation hardening process, resulting in a material with outstanding mechanical properties, especially at elevated temperatures.
This alloy is primarily used in aerospace and gas turbine applications due to its ability to withstand extreme mechanical stresses and temperatures. It also resists oxidation and carburization, even in high-temperature environments such as jet engines, rocket motors, and gas turbines. INCONEL 718 maintains its strength at cryogenic temperatures as well, making it versatile for both high- and low-temperature applications.
INCONEL 718 is trusted for its performance in critical applications, particularly in environments that require resistance to thermal and mechanical stresses while maintaining high strength and durability over long periods. Its ability to maintain properties across a broad range of temperatures makes it a preferred material for extreme industrial applications.
