General Product Description

SSAB AM Strong is a gas atomized low-alloyed powder for additive manufacturing of high strength components and tooling applications. The spherical powder is in particular suited for L-PBF (Laser Powder Bed Fusion) and DED (Direct Energy Deposition).

The printed components have a great combination of strength, toughness and hardness in as-printed condition (without additional heat treatment). The as-printed properties give a versatile use such as high-performance components for light weight constructions and engineering products. The as-printed properties also give excellent thermal conductivity and polishability for tooling inserts. The mechanical properties of SSAB AM Strong can by modified through additional heat treatment.

SSAB AM Strong is a steel grade with low CO2 emissions, available as SSAB Zero™. SSAB AM Strong is also planned for fossil-free properties (see www.ssab.com/fossilfree).

Powder Properties

Safety Information Sheet

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.
