The cost of the U.S. utility and industrial turbine corrosion is estimated to be about 700 million dollars a year. Main problems include corrosion fatigue of fossil turbine blades, stress corrosion of discs, corrosion-erosion of wet steam piping, and pitting and stress corrosion of other components. Failure statistics and recent research are revealing correlations to the material, environmental and design parameters which need all be considered in failure analysis, redesign, new design, and steam chemistry control. Interrelations and interactions between the mechanical and thermodynamic design, material properties, and steam and deposit chemistry are discussed and recommendations and corrosion design rules and requirements pertinent to these three components of turbine corrosion are given.
