FIELD: metallurgy, namely production and restoring of steel carrying parts of automatic coupler of wagons. SUBSTANCE: method comprises steps of subjecting part had been straightened with use of lateral bending pattern and heated up to temperature higher than Ac3 to lengthwise upsetting by load, consisting 0.1-0.4 of load yielding strength of cold part; then simultaneously with unloading performing rapid cooling of part surface up to temperature lower than 700 K with use of water-air mixture for blowing surface of part; completely unloading part with its further self-tempering; realizing blowing by water-air mixture containing 0.5-3.5 vol.% of water with flowrate 0.1-0.4 cubic meter/square meter s. EFFECT: enhanced quality of parts and their increased operational life period. 3 cl, 1 tbl
