Abstract High-strength sparingly doped steel possessing high hardenability has been studied. The degree of mechanical characteristics after continuous cooling with various intensities in the range of 0.02–20°C/s has been determined. Industrial heat treatment of large parts from the steel under study has been implemented using air as the quenching medium. Successful isothermal treatment using air media, as well as preliminary cementation aimed at the increase in the surface’s wear resistance, has been demonstrated.
