    Description
    Hot work tool steel. Secondary hardening steel with high strength and wear resistance in hot. Good tempering resistance. High hardenability and thoughness. Tools can be water cooled.

    Applications
    Wear resisting tools, pressure die casting tools, pressing tools for light and heavy metal. For the highest requirements we recommend UTOPMO7 ESR EFS.

    Soft Annealing
    Heat to 800-840oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 235.

    Stress Relieving
    Stress relieving to remove machining stresses should be carried out by heating to 650oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

    Hardening
    Harden from a temperature of 1030-1080oC followed by air, oil or warm bath (500-550oC) quenching. Hardness after quenching is 53-57 HRC.

    Tempering
    Tempering temperature: See the table bellow.
