Alloy 718 NACE Nickel Bar, MRO175


Alloy 718-NACE round bar is a precipitation-hardening nickel-chromium alloy containing significant amounts of iron, columbium, and molybdenum, along with lesser amounts of aluminum and titanium. In general this grade offers a combination of high strength; resistance to high temperatures and good corrosion resistance.

Hardness

  • Alloy 718 NACE round bar is stocked in the solution annealed and aged condition.
  • Hardness - 40 HRC Max
  • Tensile Strength - 150 ksi min,
  • Yield Strength - 120 ksi min

Machinability

RATING: 12% of B-1112 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.
