In the paper, the microstructures and properties of hot rolled dual phase steel DP590 with two component systems are compared and analyzed. The results show that the differences of microstructures for experimental steels are not obvious; the strength of experimental steel with C-Si-Mn-Nb component system is higher than that of experimental steel with C-Si-Mn component system, the surpluses of its yield strength and tensile strength are moderate, 81 MPa and 103 MPa respectively as well as the impact toughness and comprehensive mechanical properties are better, which are favorable for stable batch production.
