FIELD: metallurgy. SUBSTANCE: blank is heated to 1240 C, subjected to hot rolling, wound into roll at 670 C, cooled in air. Hot-rolled sheet is annealed at 700 for 19 min, and subjected to cold rolling with squeezing 50%. Obtained produce is characterized with δ 980% and Kд 0.97. EFFECT: improved quality of sheets due to reduced anisotropy and increased relative elongation. 5 tbl
