Effect of Duration of High-Temperature Tempering on the Texture and Grains of Superheated Rotor Steel

  • HEAT TREATMENT
  • Published:
Metal Science and Heat Treatment Aims and scope

The influence of the duration of high-temperature tempering after air hardening from 900 and 1250°C on the properties, texture, and brittle point of steel 25KhN3MFA is studied. It is shown that the negative effect of superheating of the steel is weakened after high-temperature tempering. Recommendations are developed for optimization of heat treatment of large forgings.
