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:
3.8 - 4.6 g/cm³ at 20 °C
12 - 20 s/50g at 20 °C
Particle size rangedrange
10 - 53 µm
Relative magnetic permeabilityμrel
1.01 [-] at 20 °C
max., None magnetic
In printed condition Prindur® 4404 is corrosion resistant according to SEP 1877 Method II (intergranular corrosion resistance test) and ASTM G48 Method E (pitting corrosion resistance test).
The powder is produced by gas atomization.
Printdur® 4404 can be processed on LPBF systems. The process parameters are similar to those of 1.4404/316L.
