Deep nitriding is used to obtain a nitriding hardness depth beyond 0.6 mm. The long nitriding processes, which are necessary to reach the high nitriding hardness depths, mostly have a negative influence on the hardness and strength of the nitrided la

In: HTM-Journal of Heat Treatment and Materials. Vol. 75 (2020) 1, 3-22. (DOI: /10.3139/105.110402)
In the field of massive forged components the mechanical engineering industry searches for processes with increasing energy and resource efficiency. The new generation bainitic steels are promising for such application because of the high strength, t
