Maraging 350


Material Characteristics

The high-performance maraging hot-work tool steel Specialis® is a newly developed alloy for LPBF processes and exclusively available at Rosswag. The mechanical properties could be easily optimized by specific heat treatments or plasma nitriding. The main advantages of the Specialis® compared to other LPBF-processable tool steels are the high temperature strength and high temperature hardness. Furthermore, on the material side, low thermal expansion, high corrosion and wear resistance as well as excellent polishability are given. This leads to a superior performance for use cases in the area of functionally optimized and thermally stres- sed moulds, dies and tools.

  1. The specified material properties were determined at room temperature. They are multidimensionally dependent on many different machine and process parameters. Without further investigation, the material properties do not constitute a sufficient basis for component dimensioning.
  2. Specific heat treatment processes lead to optimized mechanical-technological properties to meet the component requirements..
