Technological and operational properties of steels for welded turbine rotors

Welded turbine rotors are commonly produced from steels 34KhMA and 32KhM1A. Since the unit power of the rotors has increased from 300 to 1200 MW, these steels no longer satisfy the requirements for rotor materials where their strength and hardenability are connerned. It became necessary to develop n...
