• The calculation of ferrite decarburizing depth considering the effects of the chemical composition of steel and heating condition was attempted using a diffusion model and its propriety was confirmed by comparing with the experimental results. The calculation values of ferrite decarburizing depth were almost the same as the experimental values under most heating conditions, which indicates that the model is appropriate for simulation of the ferrite decarburizing depth considering the steel composition and heating condition. Only in the case where steel with a high proportion of titanium, vanadium and chromium was heated to under 973 K, did the ferrite decarburizing depth of the experiment show lower values than that of the calculation. It was speculated that small MC carbides as TiC or VC and chromium which stabilizes cementite affected the formation of ferrite decarburizing area.
