N07718 tubing, Alloy 718 plates, Inconel 718 round bars:
Inconel 718 is precipitation hardened nickel alloy containing amounts of niobium and molybdenum. Alloy 718 exhibits excellent high yield tensile and creep-rupture properties at temperatures up to 1300ºF and oxidation resistance to 1800ºF. The alloy can be supplied in the annealed condition to enhance machinability followed by subsequent appropriate heat treatments.
