General Information
Alloy 718 cold reduced nickel bar is a precipitation hardening nickel-chromium alloy containing significant amounts of columbium, aluminum, molybdenum and titanium. The alloy is cold worked after solution annealing and is typically used for high strength fasteners requiring a room temperature minimum tensile strength of 220 ksi after precipitation hardening. It is typically used at temperatures up to 900° F. This grade has oxidation resistance up to 1800° F. Alloy 718 cold reduced nickel is multiple melted usually with either a vacuum induction melt (VIM) followed by a vacuum arc remelt (VAR), or a vacuum induction melt (VIM) followed by an electroslag remelt (ESR).

Physical Properties

Machinability

  •  Rating: 12% of B-1112
  •  Typical stock removal rate: 20 surface feet/minute with high-speed tooks, 80 surface feet/minute with carbide.
  •  Carbide tooling preferred for turning operations, but high-speed steel preferred for milling (to avoid tooth chipping). Use relatively
    heavy cuts and low speeds to minimize surface work hardening. Roughing cuts are usually made before hardening,
    finishing cuts after hardening. Allow a contraction due to hardening of about 0.001 inch per inch of the workpiece dimensions.

Density

  • 0.297 lbs/in3, 8.22 g/cm3
