Uddeholm Formvar


    Uddeholm Formvar is a high performance hot work tool steel which offers a very good resistance to hot wear and plastic deformation. It is a solid upgrade choice especially from H13 and H11 forging tools on the market.

    • With good tempering back resistance and hot yield strength, Uddeholm Formvar will ensure increased tool life over H13/H11 dies. This gives a longer tool life and reduced maintenance and tooling costs.
    • Good temper resistance
    • Good high-temperature strength
    • Excellent hardenability
    • Good dimensional stability throughout heat treatment and coating operations
    • Sustainable tool steel: 97,72% recycled content
