In the paper, it is elaborated the development method for each working procedure of phosphorated high-strength IF steel BT170P1, studied the effects of C and N atoms on drawability, analyzed the reinforcing mechanism of such elements as Si, Mn and P, explained the mechanism of action of hot rolling process such as the finish rolling temperature and coiling temperature, continuous annealing process of cold rolling on microstructure and mechanical property as well as analyzed the inclusions, annealed structure of recrystallization for cold rolling, forms and distribution of precipitated phase in the microstructure. As a result, the product performances could meet the technical requirements.

In the paper, it is elaborated the development method for each working procedure of phosphorated high-strength IF steel BT170P1, studied the effects of C and N atoms on drawability, analyzed the reinforcing mechanism of such elements as Si, Mn and P, explained the mechanism of action of hot rolling process such as the finish rolling temperature and coiling temperature, continuous annealing process of cold rolling on microstructure and mechanical property as well as analyzed the inclusions, annealed structure of recrystallization for cold rolling, forms and distribution of precipitated phase in the microstructure. As a result, the product performances could meet the technical requirements.
