INCONEL® alloy 718 (UNS N07718/W.Nr. 2.4668) 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 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.

● Good mechanical properties – tensile, fatigue and creep-rupture

● Yield tensile strength, creep, and rupture strength properties are exceedingly high
● Highly resistant to chloride and sulfide stress corrosion cracking
● Resistant to aqueous corrosion and chloride ion stress corrosion cracking
● High temperature resistant
● Age-hardenable with a unique property of slow aging response that permits heating and cooling during annealing without the danger of cracking.
● Excellent welding characteristics, resistant to postweld age cracking
