Nickel chromium superalloys are often used in high-stress, high-temperature aeronautical, petrochemical and auto racing environments. The excellent high temperature strength and creep resistance derive from precipitation hardening of finely dispersed precipitates. Nickel Alloy 718 is a metal that is also highly resistant to the corrosive effects of hydrochloric acid and sulfuric acid. The favorable weldability of Nickel Alloy 718 makes this alloy suitable for additive manufacturing as well. Typical applications are high-quality components designed for thermally challenging environments such as rocket engines, gas-turbine hot sections, and heat exchangers.
