Maraging Steel MS1 - high performance steel for series tooling

Maraging Steel 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.

  • Easily machinable
  • Age hardenable up to approx. 54 HRC
  • Good thermal conductivity


  • Series injection moulding, also for high volume production
  • Other tooling applications, e.g. aluminium die casting
  • High performance parts, e.g. for aerospace applications
