Processes that develop in heating of initially hardened steels 12Kh2G2NMFT and 12KhN3A in the range of tempering temperatures, in the intercritical temperature range (ITR), and in the single-phase austenitic region are studied. The rate of relaxation of the hardened state in tempering, the intensity of formation of austenite during continuous heating and isothermal holds in the ITR, and the susceptibility to secondary growth of austenite grains in the single-phase region are analyzed.
