Abstract：The tensile properties of 780 MPa grade cold- rolled continuous annealed dual phase steel were investigated under different temper rolling reductions. The function relationships between temper rolling reduction and the tensile properties were founded. The results indicate that with the increase of the temper rolling reduction, the yield strength of the steel increases simultaneously, while the ultimate tensile strength remains the same. In addition, the uniform elongation and total elongation of the steel decrease slightly.
