In this Paper an original 800MPa cold rolled dual phase steel with low carbon and high silicon as well as some amount of Mn had been investigated in lab. The study shows that the microstructures of the steel mainly consist of ferrite, along with martensite with the content of 20%~25% which distributes homogenously on the ferrite grain boundary. The grain size of the ferrite is homogenous and with the grade of 13-14. The characteristics of the microstructure results in the excellent mechanical properties of the steel with Rp0.2=485~515MPa,tensile strength Rm=795~805MPa,total elongation A80mm=18%~19.5%,and n=0.135-0.145.
