Inconel 718 Plate

Common Trade Names: Inconel 718®, Nicrofer® 5219, Alvac® 718, Haynes® 718, Altemp® 718

Inconel 718 plate is known for their high impact, tensile and rupture strength. In many alloys, this level of strength results in a loss of welding performance. Inconel® 718 plates stand out, however, since they possess an invaluable combination of durability and weldability. In addition, this super alloy can withstand a wide range of temperature extremes and is trusted for both cryogenic and high-heat applications.

These super-alloy properties make Inconel 718 plate a popular choice for numerous industries. The alloy is ideal for hot extrusion tooling and parts, such as: rings, fasteners, casings, bolts and instrumentation components.

Inconel 718 is a precipitation hardenable nickel-based alloy designed to display exceptionally high yield, tensile and creep-rupture properties at temperatures up to 1300°F (704°C). The age-hardening response of Inconel 718 permits annealing and welding without spontaneous hardening during heating and cooling. Nickel Alloy 718 has excellent weldability when compared to the nickel-base super alloys hardened by aluminum and titanium. Nickel Alloy 718 is used in aircraft engine parts and high-speed airframe parts such as wheels, buckets, spacers, and high temperature bolts and fasteners.

Fabrication and Heat Treatment

Inconel 718 can be machined using conventional machining methods which are used for iron-based alloys. Machining operations are performed using commercial coolants. High-speed operations such as grinding, milling or turning, are performed using water-base coolants. Inconel 718 is welded using gas-tungsten arc welding, shielded metal-arc welding, gas metal-arc welding, and submerged-arc welding methods.
