    DEVELOPED TO BE TOUGH

    configure & purchase

    Uddeholm Vidar Superior is developed to be tough. With its superior toughness Uddeholm Vidar Superior is a great steel for the largest die casting dies where the safety of great cracking resistance is of the highest priority. The improved toughness makes it a suitable steel in tooling subjected to high mechanical and thermal stresses.

    • High level of resistance to thermal shock and thermal fatigue
    • Good high-temperature strength
    • Excellent toughness and ductility in all directions
    • Excellent through-hardening properties
    • Good dimensional stability during hardening.
