Nitriding of die steels 4Kh5MFS and 5Kh2MNF in a vibrofluidized bed

  • 19 Accesses

Conclusions

Nitriding of steels 4Kh5MFS and 5Kh2MNF in a vibrofluidized bed (graphite with a particle size of 0.2–0.4 mm) should be conducted at 540–570° with the ammonia entering below the bed at a rate of 1.1 liter/min, frequency of vibration 22 Hz, amplitude of vibration 2.0 mm, and acceleration of vibration 4g. After 5 h the case depth is 0.25 mm for steel 4Kh5MFS and 0.22 mm for steel 5Kh2MNF.
