The objective of this project was to provide a mechanical properties database on servic-exposed 1950 vintage CrMoV HP/IP rotor material to enable more accurate run/retire decisions for steam turbine rotors. The research team generated a comprehensive set of mechanical properties on an HP/IP rotor retired after 162,800 hours of service. Measured properties included tensile, impact, fracture toughness, notched low-cycle fatigue, creep crack growth, and creep-fatigue crack growth.
