FIELD: metallurgy.
SUBSTANCE: billet from high-manganese steel is thermally processed by heating it to 1050-1300°C, holding for one hour and cooling, hot rolling of the billet in the range of 1000 to 1300°C with a reduction of 30-90% are performed, and then warm rolling is additionally performed at a temperature of 500-700°C with a reduction of 40-70%. The invention makes it possible to obtain details of complex shape without the use of composite and welded structures, for example, to manufacture complex details of the car bodywork.
EFFECT: increasing the ductility and strength of steel.
