ժҪ The effect of hot band annealing processes, namely simulated batch annealing and continuous annealing, on microstructure, texture, grain boundary character and r-value of ferritic stainless steel was investigated. The hot band displayed a highly elongated ribbon-like structure and a pronounced deformation texture. The fully recrystallized grains were observed after continuous annealing while the ��typical�� hot-rolled structure was remained after batch annealing. Also, the ��-fibre texture formed during hot rolling almost disappeared after continuous annealing and a weak ��-fibre texture was obtained. By contract, the ��-fibre texture remained very stable after batch annealing. After cold rolling and recrystallization annealing, the favorable ��-fibre texture was achieved in the continuous annealed steel. Instead of forming the ��-fibre texture, the recrystallization texture was notably shifted toward {223}<582> in the batch annealed steel. Finally, the improvement in drawability with high r-value and low ��r-value were also displayed in sheet through the initial continuous annealing process.
