Tungsten in the Steam Turbine Blades

The reason why the blades become the main consumable parts of the steam turbines is, the vibration resistance and corrosion resistance of the conventional steam turbine blades are not high enough. In order to overcome the shortcomings of traditional steam turbine blades, it is necessary to add Mo, W, Nb, B, Ni, to strength the steel, which has good vibration resistance and corrosion resistance.
