FIELD: metallurgy.
SUBSTANCE: invention relates to ferrous metallurgy field, particularly to doping alloys for microalloying of steel by boron. The addition alloy contains, wt %: titanium 30-70, boron 0.5-5.9, aluminium 0.1-25, silicon 0.2-25, carbon not more than 2.0, iron - the rest. Additionally total amount of aluminium and silicon is from 2 up to 40 wt %, and mass ratio of titanium to boron is in limits from 5:1 up to 50:1.
EFFECT: invention provides achievement of stable assimilation of boron by metal at minimal consumption of alloying material and without necessity of additional treatment of steel melt by denitrate elements.
