Abstract

For future advanced steam turbines of 4500 psi and 1100°F, a high-temperature rotor is one of the most important components to be developed. We estimated that the usable temperature limit of existing 12Cr steel was approximately 1075°F, and then developed improved 12Cr steels. Prototype rotors were made from three types of developed steels, and were put to various evaluation tests. All three steels had creep-rupture strength exceeding that of existing 12Cr steels and were satisfactory in quality and in the other mechanical properties.
