Abstract: How the processing conditions affect the properties especially the drawability of a ferritic hot-rolled and annealed Ti-IF sheet steel was investigated. With the sample workpieces lubricated during ferritic rolling and coiled at high temperature, the maximum plastic strain ratio of sample was 1.38 with elongation over 50%. For the samples rolled with lubricating interity further annealed, the strong {111} recrystallization texture presents uniform distribution in thickness direction with low of {110} recrystallization texture even in surface layer. However, under unlubricated rolling conditions, the weak {111} texture presents ununiform distribution with high intensity of {110} recrystallization texture especially in surface layer. To acquire the deep drawability, the reheating temperature, finished temperature and coiling temperature should be 1100-1150°C, 750-800°C and over 650°C, respectively.
