    General Product Description

    SSAB AM Tough is a gas atomized advanced high strength steel powder for additive manufacturing. SSAB AM Tough is in particular suited in L-PBF (Laser-Powder Bed Fusion) and DED or LMD (Direct Energy Deposition or Laser Metal Deposition).

    SSAB AM Tough is targeted towards additive manufacturing of high strength engineering components, heavy machinery, automotive and energy sector where toughness is the most desired property.

    SSAB AM Tough is available on request as fossil-free steel powder.

                    Safety Information Sheet

                    Fossil-free steel

                    The steel in this product is a proof of concept and pilot delivery of the fossil-free steel SSAB is developing. By using hydrogen reduced sponge iron, SSAB has removed the primary source of CO2 emissions in the steelmaking, emitting water instead of carbon dioxide. Discover more at www.ssab.com.
