Material description:
The nickel content above includes cobalt. The iron content is the balance. Developed in the early 1960s, IN718 is still considered the material of choice for most aerospace engine components used below 1200°F (650°C). Inconel 718 is a precipitation-hardened nickel-chromium alloy that also contains significant amounts of iron, niobium, and molybdenum, and smaller amounts of aluminum and titanium. It combines corrosion resistance with high strength and excellent weldability, including resistance to post-weld cracking. The alloy has excellent creep rupture strength at temperatures up to 1300°F (700°C).
Applications: Aerospace, gas turbines, rocket engines, spacecraft, space shuttles, nuclear reactors, pumps, turbopump seals, and tools.
Forms: Round, flat, extruded shapes, tube, pipe, forgings, plate, sheet, strip, and wire.
