The mechanical properties of steel 30CrMnSi (30KhGSA) are studied upon optimization of the mode of heat treatment with respect to four parameters [the duration of austenitization (15 – 40 min), the temperature of the first tempering (480 – 530°C), the temperature of the second tempering (the temperature of the first tempering ± 50°C), the duration of the second tempering (60 – 100 min)] and upon changing the cooling medium in quenching, first tempering, second tempering, and second refinement. The parameters are optimized using the method of analysis on the response surface for 30 tests. The structure of the steel after the treatment by the optimized modes is studied by scanning electron microscopy, including the methods of back-scattered electrons and energy dispersive analysis.
