Is alloy 718 the same as Inconel 718?
Alloy 718, sold as Nickel Alloy 718 and Inconel 7l8, is a high-strength nickel-chromium material. This age-hardenable alloy offers excellent corrosion resistance and is easily machined. Other key properties of Nickel Alloy 718 and Inconel 7l8 include:


Excellent relaxation resistance
Can be made into the most complex components
Offer a wide temperature range of -423°F(-253°C) to 1300°F(705°C)
Excellent tensile, fatigue, creep and rupture strength
Gamma Prime strengthened
Excellent oxidation resistance up to 1800°F(980°C)
Available annealed and tempered, aged, cold worked or cold worked and aged
Due to its unique properties, Alloy 718 is popular in many different critical industries and applications, including:
Gas turbine components
Cryogenic tanks
Jet engines
Liquid fuel rocket engines and components
Fasteners and instrumentation components
Nuclear fuel element gaskets
Hot extrusion tools
Downhole shafts and strength bolts
