WebMay 1, 2024 · 1. To obtain a high case hardness it is necessary to reach, during carburizing, a saturation degree in excess of 2% C. Carburizing must be conducted at 950 or 100° C for 15 or 5 hrs. to obtain a total case depth of 1 to 1.2 mm, respectively. 2. The thickness of the layer with over 58 R c depends then on the subsequent heat treatment. WebAug 28, 2014 · The standard carburizing steel 18CrNiMo7-6 is often used when high hardenability is required. Because of its highly fluctuating price, there has always been an incentive to develop Ni-free steel grades. The 23MnCrMo5-5-2 or Jomasco 23mod has been developed for this purpose. ...
