FIELD: metallurgy.
SUBSTANCE: according to the first version wire consists of steel envelope and filler, containing vanadium in the form of ferrovanadium and admixture in the form of metallic calcium and/or silicocalcium, or mixture of metallic calcium and/or silicocalcium with silicobarium at following ratio of components, wt %: ferrovanadium 80-98, admixture 2-20. According to the second version filler contains vanadium in the form of ferrovanadium, admixture in the form of metallic calcium and/or silicocalcium, or mixture of metallic calcium and/or silicocalcium with silicobarium and ferromolybdenum at following ratio of components, wt %: ferrovanadium 30-50, admixture 2-20, ferromolybdenum 30-68.
EFFECT: increasing of plastic and viscous properties of steel, increasing of recovery grade of vanadium, also reduction of molybdenum concentration in steel with increased durability against temper brittleness development.
