ASTM B637 UNS N07718 Nickel Alloy Inconel 718 for High Temperature Application
N07718 is a Ni-Cr-Mo alloy designed to resist a wide range of severely corrosive environments, pitting and crevice corrosion.
It displays exceptionally high yield, tensile, and creep-rupture properties at high temperatures. This nickel alloy is used from cryogenic temperatures up to long term service at 1200° F(650°C). One of the distinguishing features of N07718’s composition is the addition of niobium to permit age hardening which allows annealing and welding without spontaneous hardening during heating and cooling. The addition of niobium acts with the molybdenum to stiffen the alloy’s matrix and provide high strength without a strengthening heat treatment. Other popular nickel-chromium alloys are age hardened through the addition of aluminum and titanium. This nickel steel alloy is readily fabricated and may be welded in either the annealed or precipitation (age) hardened condition.
