ASTM B983 UNS N07718 / Inconel 718 Nickel Alloy Steel Seamless Pipe and Tube
ASTM B983 UNS N07718 / Inconel 718 Nickel Alloy Steel Seamless Pipe
Inconel 718 is a Gamma Prime strengthened alloy with excellent mechanical properties at elevated temperatures, as well as cryogenic temperatures. Suitable for temperatures upto around 1300 F. Can be readily worked and age hardened.
Such conditions are typical for power generation industry,chemical, petrochemical industry, aerospace engineering. Advanced nickel-based high strength alloys traditionally have nickel and chromium as their foundation, with elements such as molybdenum, tungsten and cobalt added to confer additional solid solution strengthening. Where high temperature strength is critical, additions of aluminum, titanium and niobium, resulting in precipitation hardening , must be added.
