FIELD: heat treatment of rolled products. SUBSTANCE: after rolling at 900-1050 C metal is cooled to 675-650 C and it is allowed to stand at said temperature within 10-30 s. Mentioned above cooling is carried out at rate being more its critical value. Then fast cooling to 550-400 C takes place. Metal is then allowed to stand at this temperature to complete desired transformations. EFFECT: improves efficiency of the method.
