B.S. HR 51 Heat Treatments

  • Bars for machining: Delivery = Use condition - Solution treated + precipitation treated: Θ = (980 ±10) °C / t >= 1 h / OQ or WQ + Θ = (720 ±10) °C / t >= 16 h / AC; Billets and bars for forging: Heat treatment: Solution treated + precipitation treated Θ = (980 ±10) °C / t >= 1 h / OQ or WQ + Θ = (720 ±10) °C / t H 16 h / AC; Forgings: Delivery condition - Solution treated + precipitation treated: Θ = (980 ±10) °C / t >= 1 h / OQ or WQ + Θ = (720 ±10) °C / t H 16 h / AC.
  • The material shall be supplied in one of the following conditions:
    I) Bars for machining, forgings: Solution treated
    II) Billets and bars for forging: Hot or cold worked and subsequently machined or ground. Material of other than round section may be supplied in the descaled condition.
    III) Finished parts: Solution treated and precipitation treated.
    Solution treatment (quenching in oil or water): 980°C ± 10°C (min. 1 hour)
    Precipitation treatment (cooling in air): 720°C ± 10°C (min. 16 hours)
