ATI 80 A™ Alloy is nominally an 80% nickel - 20% chromium alloy which is strengthened by precipitation hardening through the addition of titanium and aluminum. It was introduced in England over 40 years ago, and was the forerunner of nickel-based, precipitation hardening superalloys for use in jet engines. The alloy possesses good creep-rupture properties combined with very good oxidation resistance and satisfactory high temperature fatigue characteristics. ATI 80 A™ Alloy is generally used for high strength applications up to 1,400°F (760°C), but may be used as high as 1,550°F (843°C) for short duration service. ATI employs vacuum induction melting and vacuum arc remelting to produce this alloy. Major applications are turbine blading for jet engines and stationary gas turbines, high temperature bolting, and other hot components and hardware in gas turbines.
