Printdur® HSA: High-Strength, Nickel-Free Steel for LPBF

The newly developed Printdur® HSA is characterized by the following properties:

Good processability with LPBF.

Printdur HSA is produced without the alloying element nickel. As a result, the safety regulations during the processing of the powder are significantly reduced.

Significantly increased yield strength, tensile strength and hardness compared to typical austenitic steels (like e.g. 316L).

High corrosion resistance (Pitting Resistance Equivalent Number) PREN = 36 compared to typical austenitic steels (316L = 28).

High tendency to work hardening.

High resistance to cavitation.

A subsequent heat treatment can increase the toughness.
