Bainidur® 1300 – The Low-Crack, High-Strength Forging Alloy

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.

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.
