The influences of cold rolling reduction ratio and annealing time on the stamping performance of Ti-IF deep drawing steel are studied by means of such equipment as optical microscope, X-ray diffractometer and tensile tester aiming at the phenomenon that the stamping performance of cold rolled cover annealing thick deep drawing steel is unstable. The results showed that the r value and tensile strength tended to increase and change of n value was not obvious with the increase of cold rolled reduction ratio; r value increased, tensile strength decreased and change of n value was not obvious with the extension of annealing time. The process is optimized according to the test results so that density of {111} texture is enhanced and stamping performance of product is obviously improved.
