Introduction

Maraging Steel

EOS MaragingSteel MS1 is a martensite-hardenable steel. Its chemical composition corresponds to US classification 18% Ni Maraging 300, European 1.2709 and German X3NiCoMoTi 18-9-5. This kind of steel is characterized by having excellent strength combined with high toughness. The parts are easily machinable after the building process and can be easily post-hardened to more then 50 HRC. They also have excellent polishability.

Key Benefits
easily machinable
age hardenable up to approx. 54 HRC
good thermal conductivity
