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

    Application areas

    The properties of Printdur® HSA offer a wide range of applications in mechanical engineering, e.g. food and chemical industry, pump components, the power plant industry or the automotive industy.

    Corrosion properties

    In printed condition Prindur® HSA is corrosion resistant according to SEP 1877 Method II (intergranular corrosion resistance test) and ASTM G48 Method E (pitting corrosion resistance test).

    Processing history

    The powder is produced by gas atomization.

    Processing methods

    Printdur® HSA can be processed on LPBF systems. The process parameters are similar to those of 316L. Please contact us for further information.
