The continuous annealing process of phosphorus high strength IF steel 210P1 is tested. The effects of different continuous annealing temperatures on the microstructure and mechanical properties of cold rolled strip 210P1 are investigated with such analysis methods as optical microscope, scanning electron microscope and universal tensile testing machine. The results showed that the grain size gradually increased, non-recrystallization microstructure transformed to recrystallized microstructure and form of microstructure changed from long strip to equiaxed shape with the increase of annealing temperature. The annealing microstructure of steel 210P1 was all ferrite and there was a small quantity of precipitated phase of TiN at grain boundary. The detrimental phase of FeTiP was not discovered so as to demonstrate the continuous annealing process could not cause the phase of FeTiP to be precipitated. The yield strength and tensile strength tended to decrease, elongation, n value and r value tended to increase as well as r value of steel 210P1 increased obviously especially after the annealing of 780 ℃ with the increase of annealing temperature.
