An analytical function containing the undetermined parameter was used to calculate the Jominy hardness distributions. This undetermined parameter was defined as the hardenability coefficient of steel, which is different from the conventional element coefficient and depends on the descending velocity of the Jominy curve. Therefore, the problem predicting the Jominy curve changes to one calculating the hardenability coefficient. It was demonstrated that the hardenability coefficient depends on the chemical composition under the condition of the standard Jominy test. An empirical relationship between the hardenability coefficient and the chemical composition of structural steels has been established using a subsection approach. Substituting the obtained hardenability coefficient into the distribution model of the hardness, the predicted Jominy curves exhibited very good agreements with the experimental data.
