Technological parameters
Deformed in cold and hot condition. Hot deformation is carried out at 1180−850°C. Softening heat treatment: tempering (730−750°C) or annealing (850−880°C) with slow cooling to 740 °C, cooled to 640 °C at a rate of 20°C/h. Recrystallization annealing of the strip in the bell-type furnace is carried out at 660−680°C; in a strand furnace at 730−750°C. In the structure of steel after annealing is granular pearlite with excess eutectic carbides. Secondary carbides uniformly distributed in ferrite matrix. The microstructure of cold-rolled strips includes 45−55 fine carbides in the area of 100 mm2.
