The Versatility of Nickel Alloy 718

The metal nickel alloy 718 is a widely used material that is able to resist both high temperatures and severe environments. This nickel-chromium-molybdenum alloy is commonly used in many different industries, including the aerospace and oil industries. While there are a number of other nickel-based superalloys, none are as versatile as Inconel 718.

This nickel alloy is capable of withstanding severe conditions and environments, as well as a range of corrosive chemicals. It also demonstrates outstanding strength and durability, even in the hottest areas of gas turbine engines. The versatility of nickel alloy 718 makes it a popular choice for engineering components like jet engine and high speed airframe parts, such as wheels, buckets, spacers and high temperature bolts and fasteners.

nickel alloy 718 can be easily fabricated into complex parts, and it can be welded with good results. It also has good fatigue, creep and rupture strength as well as high resistance to stress age cracking. This is due to the addition of molybdenum and niobium in the composition, which provide stiffening and help the nickel alloy retain its formability at elevated temperatures.

Nickel Inconel 718 is a precipitation hardenable nickel-chromium alloy, with additional elements of iron, molybdenum and smaller amounts of aluminum and titanium. It is designed to exhibit exceptional high yield, tensile and creep-rupture properties at temperatures up to 1300°F. The alloy’s sluggish age hardening response allows it to be annealed and welded without the risk of spontaneous hardening during heating or cooling.
