GH4169, GH169(China); NC19FeNb(France); NiCr19Fe19Nb5, Mo3(Germany); NA 51(Great Britain); Inconel718, UNS N07718(United States); NiCr19Nb5Mo3(ISO)
Alloy 718 is a high strength, corrosion resistant nickel chromium alloy designed to combine excellent strength with good fabrication characteristics. It's welding characteristics, especially it's resistance to post-weld cracking, are outstanding.
This material is generally supplied in the solution treated and precipitation hardened condition giving yield strengths in excess of 120 KSI (827Mpa).
Typical applications include both aircraft turbine engines and land-based turbines as well as liquid rocket components involving cryogenic temperatures.
The alloy is also used in various applications for oil/gas well down-hole and well head components. It is also used for fasteners and instrumentation parts.
