1.2343 | X38CrMoV5-1 +QT Long-term plasma-nitrided

Numeric designation1.2343
Chemical designationX38CrMoV5-1
State+QT Long-term plasma-nitrided (42h)
Etching3% Nital

This quenched and tempered hot-work tool steel was plasma-nitrided for 42 hours at 540 °C in a long-term process. A thin, low-porosity compound layer (average thickness: 7 µm) is present. The dark etched diffusion layer is approx. 335 µm deep. Nitride seams have formed along the grain boundaries. The basic structure consists of tempered martensite. The measurement of the nitriding depth in the course of hardness resulted in a NHD of 0.34 mm. The hardness limit was 560 HV0.5.

  • Pore line: only isolated pores
  • Bond coat thickness VS | CLT: 7 µm
  • NHD 560 HV0.5 = 0.34 mm
