FIELD: heat treatment of metals and alloys. SUBSTANCE: invention can find use in mechanical engineering to raise plastic properties of steel blanks passed through plastic metal working in particular. Blanks of predominantly medium carbon steel are heated in two stages by electric current of certain density with pause in supply of current during heating. EFFECT: provision for control over physical and mechanical characteristics, intensification of process of thermal treatment, decreased power consumption. 1 c, 4 dwg, 1 tbl
