The invention relates to the metallurgy. A method for the production of low-alloyed steels with carbonitride strengthening includes steel melting in the melting unit, introduction of carbamide to the melting unit by portions by 0.05-0.20 kg/t in the form of the special ligature on the basis of the grinded standard ferro-alloy, introduction of aluminium containing materials and to the ferrotitanium. The invention allows to nitrogen fixation by the melt and to eliminate the possibility of castings lack.
