Inconel 718 is a precipitation-harden able, nickel-chromium alloy containing also-significant amounts of iron, niobium and molybdenum, along with lesser amounts of aluminum and titanium. It combines corrosion resistance and high strength with outstanding weld ability, including resistance to post weld cracking. Inconel 718 has excellent creep-rupture strength at temperatures to 1300°F (700°C).
Inconel 718 is used in gas turbines, rocket motors, space-craft, nuclear reactors, pumps and tooling. Standard product forms are round, flats, extruded section, pipe, tube, forging stock, plate, sheet, strip and wire.
