SEW 60 WCrV 7 Heat Treatments


  • Soft annealing: Slowly heated at 710-750°C, held for several hours, slowly cooled, preferably in the furnace.
    The soft annealing is most appropriate for machining and cold working and provides the most favorable initial structure for tool hardening.

    Hardening: Preheated at 500-600°C and then heated faster at 870-900°C, quenched in oil.
    Temperature of oil should be approx. 50°C. When quenching in aqueous salt solutions, the temperature of the quenching agent may rise to 100°C.
    Hardening immediately after forging without cooling and annealing is inappropriate because of the risk of cracking.

    Stress relief annealing: Slowly heated at 600-650°C, held for 1-2 hours, slowly cooled in the furnace.
