A whitepaper has been posted to the voestalpine Böhler Edelstahl website that describes the company’s new AMPO M789 maraging steel powder for 3D printing. The Austria-based manufacturer of tool steels, high-speed steels, and specialty metals claims the patent-pending alloy combines the compressibility of maraging steel with the corrosion resistance of 17-4PH stainless steel.
The alloy attains a post-heat treatment hardness of up to 52 HRC. It’s recommended for DMD (direct metal deposition) and SLM (selective laser melting) 3D printing, as well as forging, injection molding, and other industrial operations.
