The effect of annealing temperature after cold rolling on the microstructure,texture and drawability of ferritic stainless steel was investigated in detail.The grain size increased substantially with the increase of annealing temperature,from 26 μm at 850℃ to 48 μm at 1 000℃.With further increase of annealing temperature(to 1 050℃),the trend of grain growth was more evident,which illustrated the grain size sensitivity.After being annealed at different temperatures,all sheets were dominated by the γ-fiber texture with a very weak α-fiber texture.The intensity of the γ-fiber texture increased with the increase of annealing temperature.A few Goss texture {110} 001 were found when the annealing temperature increased to 1 050℃.The average r-value showed a peak at the annealing temperature of 950℃.
