FIELD: metallurgy.
SUBSTANCE: to improve plastic characteristics at keeping of high strength properties the steel is produced which contains, wt %: carbon 0.30-0.35, manganese 0.50-0.70, silicon 0.20-0.37, phosphorus less than 0.020, silicon less than 0.010, chrome 0.40-0.70, nickel no more than 0.15, copper no more than 0.20, aluminium 0.015-0.035, titanium 0.03-0.05, boron 0.002-0.005, calcium 0.0001-0.005 and iron the rest.
EFFECT: composition for fabrication of roll stock with round cross section for producing of high-strength fasteners will allow to increase profitability of trading of hot roll with improved consumer properties.
