SSAB AM Engineering is a gas atomised low-alloyed powder for additive manufacturing of high strength engineering components. SSAB AM Engineering is in particular suited in L-PBF (Laser-Powder Bed Fusion) and Direct Energy Deposition (DED or LMD).
The spherical powder enables an optimal combination of strength, toughness and high levels of isotropy in the as-built condition.
SSAB AM Engineering is a steel grade with low CO2 emissions and planned for Zero™ and fossil-free properties (see www.ssab.com/fossilfree).
Standard particle size distribution.
| L-PBF | 20 - 53 µm 1) |
|---|---|
| DED | 45 - 106 µm 1) |
1) Max 5% over and under size.
Measurement of particle size distribution is according to ISO 13322-2 (Dynamic image analysis methods).
Other particle size distributions can be arranged upon agreement.
