PROPRIETARY BE1248 Heat Treatments

  • Annealing at 650 - 690°C (1200 - 1275°F)
    Stress relieving around 650°C (1200°F)
    Hardening: Austenitizing at 830 - 860°C (1525 - 1580°F), holding for 1.5 x material thickness and quenching in oil.
    Tempering: slow heating to tempering temperature immediately after hardening, holding in furnace for minimum 2 h (recommended 4 - 6 h). Cooling in the furnace until the temperature have fallen bellow 100°C (210°F).
