3. Results and discussions The results of numerical analysis under the specified operating conditions are shown in Figures 7-14. The data obtained make it possible to compare the performance characteristics of springs made of different materials and evaluate their reliability in various conditions. The maximum deformation of springs made of 55Si2 steel reaches 98,196 mm, whereas for 60Si2CrVA steel it is 82,217 mm (Fig.

3. Results and discussions Figs. 3 and 4 show the temperature distribution over the section of the product. The surface temperature after 1000 seconds is 892 °C. The temperature difference between the surface and the core of the product is 1.25 °C. Since the temperature difference is small, the internal stresses during the heating process are minimal. Analyzing the temperature dependence on the heating time (Fig.
