About Alloy 718

alloy 718

What is Alloy 718?

Alloy 718 is a high-strength, corrosion-resistant nickel chromium material used at -423° to 1300°F.

The age-hardenable alloy can be readily fabricated, even into complex parts. Its welding characteristics, especially its resistance to postweld cracking, are outstanding.

Examples of these are components for liquid fueled rockets, rings, casings and various formed sheet metal parts for aircraft and land-based gas turbine engines, and cryogenic tankage.

It is also used for fasteners and instrumentation parts.

Alloy 718 is available as pipe, tube, sheet, strip, plate, round bar, flat bar, forging stock, hexagon, wire and extruded section.
