Material Notes:
Nickel content to balance. Age-hardenable superalloy with very good strength at temperatures up 980°C (1800°F), can be cold-formed in the annealed condition, may also be hot formed at 1040°C (1900°F) and above, good resistance to gas turbine combustion gas environments at temperatures up to 870°C (1600°F). Widely used as a wrought material for forged and fabricated gas turbine and aerospace components. Data provided by the manufacturer, Haynes International, Inc.
