    Technological properties

    Property
    Application areas

    Bainidur® 1300 was developed for forging parts with highest requirements.

    General machinability

    Very good

    Processing history

    The powder is produced by gas atomization.

    Welding

    Due to the low carbon content Bainidur® 1300 has a superior weldability. The formation latent heat during the bainitic transformation reduces thermal stresses and therefor the risk of cracking.
