A method for production of cast low-alloy steels with carbonitride strengthening comprises steel melting in a melting unit, deacidification thereof, addition of carbamide, metal drawing into steel teeming ladle, introduction into the latter of aluminum-containing materials and ferrotitanium, pouring of metal into forms. Addition of carbamide is carried out in the melting unit in portions of 0.05-0.20 kg/t in the form of special in addition alloy based on grinded standard ferroalloy.
