Abstract
Welded turbine rotors are commonly produced from steels 34KhMA and 32K hMIA. Since the unit power of the rotors has increased from 300 to 120 0 MW, these steels no longer satisfy the requirements for rotor materi als where: their strength and hardenability are concerned. It became n ecessary to develop new deeply hardening and well weldable high-streng th steels. The present paper concerns the results of an all-around ana lysis of the mechanical properties and weldability of industrially mol ten metals.
