Since their materials were used in extremely high temperature and strong corrosive environments, aerospace and gas turbines had been the greatest difficult task of integrated systems engineering. Severe requirements for material deformation requirements, creep, fatigue, slow crack propagation and safety are put forward. Gina company relies on core technologies of GNSVR (Gina New Strong Vacuum Reaction refining), and GNSTM (Gina New Superheat Treatment of Melt refining) to prepare vacuum electrodes following re-melt or triple-melt to ensure long life reliability of super alloy materials.
