Nickel Alloy 718, Inconel® 718

Sold as both Nickel Alloy 718 and Inconel® 7l8, alloy 718 is a high strength nickel-chromium material. This age-harden alloy offers outstanding corrosion-resistance and exhibits characteristics that make it easy to work with for fabrication purposes. Other key properties of Nickel Alloy 718 and Inconel 7l8 are:

  • Excellent relaxation resistance
  • Can be fabricated into even the most complex parts
  • Offers a wide temperature range -423°F(-253°C) to 1300°F(705°C)
  • Outstanding tensile, fatigue, creep, and rupture strength
  • Gamma Prime strengthened
  • Excellent oxidation resistance up to 1800°F(980°C)
  • Available in annealed temper, aged, cold worked, or cold worked and aged

Because of its unique array of properties, alloy 718 is popular with a number of different critical industries and applications including:

  • Gas turbine components
  • Cryogenic storage tanks
  • Jet engines
  • Liquid fueled rocket motors and components
  • Fasteners and instrumentation parts
  • Nuclear fuel element spacers
  • Hot extrusion tooling
  • Down hole shafting and strength bolting

Nickel Alloy 718 and Inconel 7l8 consists of over 50% nickel and of a number of different elements:

  • Ni 52.5%
  • Fe 18.5%
  • Cr 19%
  • Cb+Ta 5.13%
  • Mo 3.05%
  • Ti 0.9%
  • Al .5%
  • Co 1% max
