Technological parameters

Deformable in cold and hot state. Hot deformation is carried out at 1180-850 °C. Softening heat treatment: tempering (730-750°C) or annealing (850-880°C) with delayed cooling to 740°C, cooling to 640°C at the rate of 20°C/h. Recrystallization annealing of the strip in the bell furnace is carried out at 660-680°С; in the broaching furnace at 730-750°С. In the structure of steel after annealing there is grained pearlite with excess eutectic carbides. Secondary carbides are evenly distributed in the ferrite matrix. The microstructure of the cold-rolled strips includes 45-55 small carbides in an area of 100 mm2.
