    General Product Description

    Toolox® 44 is a steel already heat treated to the final properties.Thus saving time, costs and risks associated with heat treatment.

    The very high strength is combined with a high and guaranteed toughness as well as an excellent fatigue resistence. Making Toolox® 44 the ideal choice for the most demanding engineering and mould and die applications.

    Toolox® 44 can be surface hardened with methods like nitriding, laser and induction. Giving the possibilities to even further improve the performance.

    Dimension Range

    Toolox® 44 is available as plates in thicknesses between 6.0 - 130.0 mm. Other dimensions can be available on request.

            1) Unless otherwise agreed, transverse impact testing according to EN 10025-6 option 30 will apply. For thicknesses between 6 - 11.9 mm, sub-size Charpy V-specimens are used. The specified minimum value is then proportrional to the cross-sectional area of the specimen compared to a full-size specimen (10 x 10 mm).
