Alloy 718 (UNS N07718 / 2.4668) is a high-strength alloy with excellent mechanical properties at elevated temperatures, as well as cryogenic temperatures from -253°C to 705°C. It combines high strength in the aged condition with good corrosion resistance and weldability. Typically sold in the solution annealed temper, but can be ordered aged, cold worked, or cold worked & aged.
