Heat Treatments

  • Carburized: 900-925°C, quenched in oil; Reheat: 845-870°C; Tempered: 120-175°C.
  • Heated to a suitable temperature at or above the upper critical temperature, but not exceeding 925°C (1700°F), held a sufficient length of time to attain essentially uniform temperature throughout, and cooled as appropriate for the condition specified.
