The alloy’s oxidation resistance is good under conditions of frequent thermal cycling, and in continuous exposure to temperatures up to 1900°F (1038°C). It has performed well in atmospheres found in gas turbine engine service and in salt spray environments. Solution-treated material offers the best levels of corrosion resistance.
Mechanical properties reported for specimens heat treated for optimum creep and stress-rupture properties: Solution treat at 1080°C (1975°F)/4h/AC. Then stabilize by reheat to 845°C (1550°F)/24h/AC. Then age harden by reheat to 760°C (1400°F)/16h/AC.
