EOS MaragingSteel MS1 DMSL on EOS M290 400W Product Information -:- For detailed product information, please contact sales. -: # EOS MaragingSteel MS1 ## DMSL on EOS M290 - 400W Laser Configuration --- ### **Product Overview** **EOS MaragingSteel MS1** is a proprietary gas-atomized, precipitation-hardenable steel powder engineered for **Direct Metal Selective Laser Melting (DMSL)** on the **EOS M290 system with the standard 400W fiber laser configuration**. This system represents the **industrial workhorse** for producing high-density, ultra-high-strength maraging steel components via Laser Powder Bed Fusion (LPBF). The 400W laser provides the optimal balance of power, speed, and melt pool control for MS1, enabling the fabrication of complex geometries that are subsequently age-hardened to achieve mechanical properties exceeding 1950 MPa UTS. This material-machine combination is the **industry benchmark** for additive manufacturing of high-performance tooling and lightweight structural components. --- ### **Chemical Composition (Weight %) - EOS MS1 Powder Specification** | Element | Specification Range | Key Role in DMSL Process | |---------|---------------------|--------------------------| | **Nickel (Ni)** | 17.0 - 19.0 | Forms the primary martensitic matrix; critical for as-built toughness and age-hardening response. | | **Cobalt (Co)** | 8.5 - 9.5 | Drives precipitation kinetics; essential for achieving peak aged strength. | | **Molybdenum (Mo)** | 4.5 - 5.2 | Primary precipitation hardener (forms Ni₃Mo). | | **Titanium (Ti)** | 0.6 - 0.8 | Secondary precipitation hardener (forms Ni₃Ti).
