1. Brief introduction:

   It’s a Ni-Fe-Cr alloy containing Ti and Al for precipitation hardening and Mo for solid-solution strengthening.

   It has high-yield strength and creep resistance at temperatures to about 1110℉（600℃）。A substantial iron content enables the alloy to combine high strength with good forging characteristics.

   Used in gas turbines for discs and shafts.
