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