FIELD: metallurgy.
SUBSTANCE: steel containing 0.16-0.32 wt % of carbon is melt out of charge consisting, mainly, of pellets. Liquid steel is successively alloyed with manganese at amount of 0.80-1.60 wt %, aluminium at amount of 0.015-0.060 wt % and titanium introduced upon preliminary addition of ferroalloys calculated in terms of residual contents not less, than 0.03 wt %. Boron is introduced into melt at amount of 0.001-0.008 wt %. Work-pieces for rod fabrication are hot-rolled. There is performed process controlled rod accelerated cooling from a critical temperature interval, which results in forming uniform double-phase ferritic-martensite structure corresponding to a soft ferritic matrix with inclusions of hard martensite constituent.
EFFECT: reduced responsiveness of rods to concentrators of loads at big deformations; increased plasticity of material.
