The influence of annealing temperature on the hardness， microstructures and textures of the cold-rolling   Nb+Ti-IF steel were studied in this paper. The results show that the hardness decreases and the grains become e-  quiaxed when the annealing temperature increases. Theγ fibre texture becomes stronger while theα fibre texture be-  comes weaker with the annealing temperature increasing. The annealing temperature for the cold-rolling Nb+Ti-IF   steel should be controlled at about 800℃ for saving the energy and processing.
