INCONEL 718(UNS N07718) is a high-strength corrosion resistant nickel chromium material. The age-hardenable alloy can be readily fabricated. even into complex parts. Its welding characteristics. especially its resistance to post weld cracking, are outstanding. The ease and economy with which INCONEL alloy 718 can be fabricated, combined with good tensile, fatigue creep, and rupture strength, have resulted in its use in a wide range of applications. Examples of these are components for liquid fueled rockets, rings, casings and various formed sheet metal parts for aircraft and land-based gas turbine engines, and cryogenic tankage. It is also used for fasteners and instrumentation parts.
