Description

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.
  • Related Standards
