and the cold-rolled sheet is annealed at 1 000 °C. The effect of cold rolling reduction on structure

texture and mechanical properties of steel Cr22Mo is studied by optical microscope

X-ray diffractometer (XRD) and universal tensile testing machine. The results show that with increasing cold rolling reduction the structure of cold-rolled and cold-rolled-annealed sheet is finer

the intensity of recrystallized texture {111}increases

average plastic strain ratio r value increases and the plane anisotropy △r decreases

and the increase of cold rolling reduction markedly improves the fbimability of cold-rolled annealed sheet of steel Cr22Mo.
