General Product Description

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, available with SSAB Zero™ steel. SSAB AM Engineering is also planned for fossil-free properties (see www.ssab.com/fossilfree).

                      SSAB Zero™

                      SSAB Zero™ is made of recycled steel and produced with fossil-free electricity and biogas. It has virtually no fossil carbon emissions during steel production, without mass balancing allocation of emission reduction or carbon emission offsetting. SSAB Zero™ has the same quality and properties as the traditional steel versions. More details are given in SSAB Zero™ Certificate of Carbon Emissions at www.ssab.com.
