Just recently, the HY-Industry Special Alloy Factory was successfully rated as a model of military-civilian integration enterprises by Jiangsu Province. The local government funded the renovation of the plant and installed the dead-end monitoring. Gas turbine forgings will be manufactured in a special workshop and separated from military projects. The picture below shows the recently completed gas turbine Inconel 718 forgings, which will be exported to Germany.

Inconel 718 Characteristic as below:
1.workability
2.High tensile strength,endurance strength,creep strength and rupture strength at 700℃.
3.High inoxidability at1000℃.
4.Steady mechanical performance in the low temperature.
5.Good welding performance.
Inconel 718 Metallurgical structure:
Inconel 718 is Austenitic structure, precipitation hardening generate “γ” made it excellent mechanical performance. G rain boundary generate “δ” made it the best plasticity in the heat treatment.
Inconel 718 Corrosion resistance:
Inconel 718 with extremely resistance to stress corrosion cracking and pitting ability in high temperature or low temperature environments, especially the inoxidability in the high temperature.
Inconel 718 Application field:
The elevated temperature strength, excellent corrosion resistance and workability at 700℃ properties made it use in a wide range of high requirement environments.
