Description

Bainidur® 1300 is designed especially for robust processes with low dependence of mechanical properties on size and a low risk of cracks or distortion during cooling. Usually the hardness values are between 36 and 40 HRC.


Bainidur® 1300 is an optimum solution for a lot of forging applications regarding economic, mechanical properties and process stability. The newly developed Bainidur® 1300 is characterized by the following properties:


  • Good processability with LPBF.
  • High strength and toughness.
  • Excellent case hardening and carbonitriding properties.
  • Related Standards

    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.
