The invention relates to ferrous metallurgy. A method comprises the obtaining of steel blank, heating of blank, hot rolling and interrupted quenching by water stream in closed chamber up to of set average weight temperatures with self-tempering. The blank is obtained from steel with contents of carbon of 0.12... 0.24 %, quenching is carried out to average weight temperature of 540 ... 660 °C, at that with the increase of carbon content in steel in specified the average weight temperature is increased on 15... 20° C on each 0.02 %.
