Parts using the Maraging Steel powder have chemical composition corresponding to US grades18% Ni Maraging 300, Europe 1.2709 grades, and German X3NiCoMoTi 18-9-5. This kind of steel possess excellent mechanical properties. By simple using thermal age-hardening treatment, ultra-high strength, hardness and plasticity can be achieved.
The Maraging Steel steel are very easy to machine after the forming process in the 3D printer, and if aged treated (480-490 ℃, 5-6 hours) properly, it is easy to increase its hardness to 50HRC or more. The subject can also be further processed with EDM, welding, sandblasting, polishing and coating if required.


SLM, SLS, Laser Cladding, EBM and other technology based on the same functionality.
