Abstract: The properties after annealing and texture of a Ti-IF steel were investigated after different hot rolling reductions in ferrite region at different finished rolling temperatures. The results showed that the IF steel has better deep drawability, higher mechanical and texture strength and elongation if the hot rolling temperature was low with big reduction in ferrite region. The texture of cold rolled IF steel is the typical conventional cold texture, i.e., partial <110>//RD fibers and global <111>//ND fibers. After annealing for recrystallization, the strength of <110>//RD fibers decreases greatly and then transform into <111>//ND recrystallized fibers. Therefore, the texture strength of <111>//ND increases greatly. It was proved that among all the cold rolled specimens, the one hot rolled finally at 750°C. with total reduction of 80% has the highest strength of <111>//ND recrystallized fibers.
