Zusammenfassung:metallurgy, namely plastic metal working, particularly manufacture of cold rolled band. SUBSTANCE: method comprises steps of hot rolling, etching, cold rolling with reduction value (5-20)% and additional double-stage annealing at (350-400)C and (600-700)C. Method provides manufacture of band suitable for next cold forging. EFFECT: enhanced quality of surface of band with improved mechanical properties. 1 ex
