Purpose: The aim of the investigation was to verify if published data for calculation of the hardenability of steel can be used for calculation of hardenability of cast steel and the optimal selection of these data for obtaining the best agreement between calculated and experimental data. Design/methodology/approach: The analysis of the hardenability of low alloy cast steel was carried out using Jominy test and analytical Grossmann method. The optimal data for calculation of ideal critical diameter, Di and Jominy curve were selected. Findings: The hardenability curves of cast steel measured on different planes of Jominy test show scatter on the contrary to forged steel Practical implications: Results of investigations prove that data for calculation of hardenability parameters used for steel can be applied with sufficient accuracy for calculation the hardenability of cast steel. The hardenability of cast steel shows scatter of results. Originality/value: The analysis of the hardenability of cast steel can be carried out using the same data as for forged steel.
