Zusammenfassung:	FIELD: metallurgy. ^ SUBSTANCE: invention refers to metallurgy, particularly to production of rolled sections in bars with diameters from 12 to 34 mm. To upgrade the level of commercial characteristics the rolled section is produced from steel containing mass %: C-(0.58-0.63), Mn-(0.60-0.90), Si-(1.60-2.0). Cr-(0.20-0,40), Ni-(0.005-0.15), Cu-(0.005-0.15), S-(0.005-0.015), N-(0.005-0.01), As-(0.0001-0.03), Sn-(0.0001-0.02), Pb-(0.0001-0.01), Zn-(0.0001-0.005), the rest being iron and impurities - the rest, at the ratio: (As+Sn+Pb+5Zn)-
