| Abstract: | In connection with the actual operations of medium and thin slab continuous casting and continuous rolling production line in Angang, 600 MPa grade hot rolled C-Si-Mn-Cr system dual-phase steel sheet is developed based on the suitable microalloying composition design and TMCP technology. The microstructure of the developed steel sheet mainly consists of a great deal of ferrite and little martensite with good mechanical properties. Its tensile strength is more than 600 MPa, yield ratio less than 0.70, elongation A80more than 19.0% and n value over 0.15,all of which can meet the requirements specified in national standards. |
