The results of verification of specialized software developed on the basis of freely distributed open-source software are presented. The essence of the modification was to expand the limits of the chemical composition for which the software allows correct calculations, as well as to expand the capabilities of the software. In the current work, the results of constructing our own isothermal decay diagrams of supercooled austenite using modified software were compared with similar diagrams for ShKh15 steel and its imported analogues based on experimental data available in the domestic and foreign literature. It is shown that, in general, according to the verification results, the modified software copes with the tasks of constructing diagrams. The correlation coefficient between the software and experimental diagrams for ShKh15 steel is at least 0.76, which is sufficient to solve most production problems, which are primarily based on determining the optimal mode of heat treatment of steels depending on the chemical composition of the steels. In addition to constructing isothermal and thermokinetic diagrams, the modified software allows you to calculate the hardenability depth for steel with a specific chemical composition using the DFB (distance to the first appearance of the bainite) method, as well as plot the phase state of steel depending on the heating temperature, which in turn allows you to calculate the final phase state of the steel after quenching. And thus, it is possible to predict the approximate amount of residual austenite in hardened high-carbon alloy steels of the ShKh15 type, the content of which, for example, is critical for precision parts of fuel equipment operating under severe operating conditions.
