Heat treatment of NPP steam turbine parts from steel 26KhN3M2FAA

  • Published:
Metal Science and Heat Treatment Aims and scope

Abstract

The process of final heat treatment of nuclear-power-plant steam turbine parts produced from steel 26KhN3M2FAA is developed. The quality of the metal of a commercially produced disk is studied. Conditions for obtaining a high set of mechanical properties in steel 26KhN3M2FAA combined with a reduced temperature of the ductile-brittle transition (semibrittleness temperature) are determined.
