        Manufacturing of Tool Steel Bar:

        - Cold rolling, slitting and edge processing

        - Heat treatment: annealing, tempering, hardening

        - Cold finishing and polishing

        Heat Treatment:

        Normalizing:

        Normalizing temperature: 860-900oC.

        Soft Annealing:

        Heat to 760-800oC, cool slowly in furnace.

        This will produce a maximum Brinell hardness of 217.

        Stress Relieving:

        Stress relieving to remove machining stresses should be carried out

        by heating to approx. 650oC, holding for 1-2 hours at heat,

        followed by air cooling. This operation is performed to reduce distortion during heat treatment.
