With the development requirements of lightweight of automobile, the 590 MPa grade cold-rolled dual phase steel for structural parts is successfully researched and developed through the chemical composition design with C-Mn-Cr alloy system combining with reasonable hot rolling, pickling tandem cold rolling and continuous annealing processes based on the advanced equipment and technological characteristics of Baotou Steel in order to meet the requirements of car body safety and environmental protection. The mass production and application of users show that all the mechanical properties of cold-rolled dual phase steel HC340/590DP could meet the technical and user requirements.
