Electroslag processed steel is of interest for rotor manufacture and other compo¬nents of electric power generating units. Electroslag processing has production advantages for the steelmaker and electroslag products have been found to have numerous features of advantage to rotor manufacturers. Electroslag processed steels are cleaner and more homogeneous in structure and chemistry than conventionally processed steels, and excellent combinations of strength, ductility, and toughness can be obtained as a result of those characteristics. There are other attractive features of electroslag processing and products such as high forging yields from ingots and low rejection rates of forgings. Collectively, the good characteristics of electroslag processed steels afford a promise for higher quality rotors and, further along in the development of this technology, larger high-quality rotor forgings than are currently available from conventional techniques.
