..., to reduce high temperature wear. One disadvantage of nitriding, however, is the difficulty it imposes on the reworking of tools or dies. Hot-work steels should be hardened and tempered before being nitrided, but should be neither decarburized nor carburized. The quality and depth of the nitrided case...

Additionally, the amount of nitride-forming elements increases the absolute value of compressive residual stresses ( Fig. 26 ) but minimizes the depth of the influenced surface layer. The cause of this is that nitrogen is bound by the nitride...
