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
• Downhole shafting and strength bolting
