FIELD: metallurgy.
SUBSTANCE: hot-rolled products are annealed at 770-790°C for 3-4 hours, cooling with a furnace down to 660-680°C, soaking for 3-4 hr, cooling with the furnace down to the ambient temperature, primary drawing with the compression extent of 12-13%, isothermal treatment by patenting at 540-560°C, and then secondary drawing with the compression extent of 7-8%.
EFFECT: production of required mechanical characteristics of rolled products due to provision of even structure of patenting sorbitol.
