Inconel 718 (UNS N07718) was developed for use in the aircraft gas turbine engine, but its unique combination of room temperature strength and aqueous corrosion resistance makes it a candidate for oilfield fasteners, valves, drill tools and completion equipment.

Inconel 718 is a high-strength, corrosion-resistant nickel chromium material used at -423° to 1300°F. 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 UNS N07718 Alloys 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.
