EOS MS1 Maraging Steel Sintered on EOSINT M 270
Categories:	Metal; 3D Printing/Additive Manufacturing Metal; Ferrous Metal; Maraging Steel
Material Notes:	Steel powder processed by DMSL. This steel has very good mechanical properties, and is easily heat-treatable using a simple thermal age-hardening process to obtain excellent hardness and strength. This material is ideal for many tooling applications (DirectTool) such as tools for injection molding, die casting of light metal alloys, punching, extrusion etc., and also for high performance industrial and engineering parts, for example in aerospace and motor racing applications. EOS®, EOSINT®, and DMLS® are registered trademarks of EOS GmbH. Information provided by Axis Prototyping.
Key Words:	US classification 18% Ni Maraging 300, European 1.2709 and German X3NiCoMoTi 18-9-5
Vendors:	Proto3000 provides design tools, 3D printers, additive manufacturing processes, metrology technologies, high-performance materials, and part-finishing automation.
