Description

Printdur® Powderfort (~1.2709) is a precipitation hardening tool steel. The grade is similar to 1.2709 in terms of alloying, but without the elements titanium and aluminum. However, the mechanical properties are identical to those of 1.2709. Printdur® Powderfort is characterized by the following properties:


  • Good processability with LPBF.
  • High yield and tensile strength combined with good toughness.
  • Simple and distortion-free heat treatment.
  • High hardness of approx. 52 HRC after heat treatment.

  • These properties make Printdur® Powderfort the first choice when components exposed to high mechanical stresses are produced by Additive Manufacturing.
