 Customized Inconel 718 forged parts shipped in Europe.(HY-marketing departmentes)

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.
