Uddeholm Unimax


    Uddeholm Unimax is a high hardness hot work tool steel which provides great wear resistance even over extended time at elevated temperatures. It performs very well in precision forging and hot stamping.

    • Improved durability and wear resistance in molding processes that wear hard on the mold like long run production, molding of reinforced plastics and compression molding
    • Longer tool life and a smoother production run with fewer disturbances for maintenance due to the high ductility
    • Problem solver in severe cold work applications where high chipping resistance is required
    • The high hardness and toughness together with the good dimension stability makes Unimax suitable as a substrate steel for surface coating when needed
    • The very good hardenability and the unique properties profile of Unimax make it especially suitable for larger molds. Unimax is therefore supplied in larger dimensions
    • Excellent toughness and ductility in all directions
    • Good wear resistance
    • Good dimension stability at heat treatment and in service
    • Excellent through-hardening properties
    • Good resistance to tempering back
    • Good hot strength
    • Good thermal fatigue resistance
    • Excellent polishability
    • Sustainable tool steel: 86,94% recycled content
