A software simulation tool, CarbonitrideTool©, has been developed to predict the Nitrogen and Carbon concentration profiles in selected steels. In this paper, the introduction of the software will be presented. In additional, the enhancement has been made to improve the CarbonitrideTool©. The diffusion of nitrogen increases the amount of retained austenite (RA) by changing the Ms temperature. In this paper, the modification has been made to calculate the RA fraction. The empirical prediction of microhardness profile will be presented. The verification results will be discussed.
