Description

Printdur® 4404 (1.4404 / 316L) has established itself within additive manufacturing as the allrounder in the field of iron-based alloys. Printdur® 4404 is characterized by the following properties:


  • Good processability with LPBF.
  • Good mechanical properties.
  • High PREN of 36 (Pitting Resistance Equivalent Number) and therefore a high corrosion resistance.
  • Good resistance to oxidation.
  • Equivalent Materials

    This material data has been provided by Deutsche Edelstahlwerke Specialty Steel (DEW).

    "Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
    All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
    Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
