The tested steel Cr22Mo 200 mm cast slab is heated at 1 150 °C for 150 min
hot-rough-rolled with 7 passes- finishing rolled with 7 passes to 4. 0 mm hot-rolled coil
annealed at 980 ~ 1 030 °C and cold-rolled to 0. 8 mm sheet and annealed at 950 〜1 020 °C. The effect of finishing rolling temperature 850 °C and 800 on structure
texture and formability of steel Cr22Mo has been tested and studied. Experimental results show that with decreasing finishing rolling temperature the structure of cold-rolled sheet fines
the recrystallized texture increases
the average plastic strain ratio r value increases and the plane anisotropy Ar value decreases
therefore the formability of cold-rolled sheet markedly improves by decreasing finishing rolling temperature.
