NB 40CrNi2MoV Heat Treatments

  • The heat treatment, should include the following process:
    - austenitizing at between 820°C and 885°C,
    - quenching by immersion,
    - tempering at a temperature which will produce the requisite properties, followed by still air cooling. Nominal holding temperature shall be between 590°C and 630°C for a minimum time of 4 hours.
