Parts built with EOS MaragingSteel MS1 are characterized by having very good mechanical properties and being easily heat-treatable using a simple thermal age-hardening process to obtain excellent hardness and strength. Main Characteristics: - The parts are easily post-hardened to more than 50 HRC
- The parts can be machined, spark-eroded, welded, micro shot-peened, polished and coated
- Chemical composition corresponding to 18Ni300 and M300
Typical Applications: - Injection molding tools & inserts
- Mechanical engineering parts
Heat treatment procedure by solution treatment at 940 °C (1,724 °F) for 2 hours, air cooling to room temperature, age-hardening at 490 °C (914 °F) for 6 hours, air cooling.Information provided by EOS GmbH (Electro Optical Systems). |
