UNS N07718, W.Nr. 2.4668
Inconel® 718 is a precipitation-hardenable nickel-chromium alloy also containing significant amounts of iron, niobium and molybdenum along with lesser amounts of aluminium and titanium. The alloy combines corrosion resistance and high strength with oustanding weldability including resistance to post-weld cracking. Inconel® 718 has excellent creep rupture strength at temperatures to 700°C. The alloy is used in gas turbines, rocket motors, spacecraft, nuclear reactors and pumps. Recommended filler metal for welding is Inconel® 718.
