In order to meet the increasing need for N6/Q235 clad plates, the method of combining plates stocks before rolling and technical process parameters of hot rolling clad plates were conformed, through test research on hot rolling technical process. According to study of metal tissue, break profile tissue, and interfacial spread, it was proved that the clad plates were excellent in tissue, property and conjoint ratio. Through the examination and analysis of the targets of mechanical property, it was confirmed that the clad plates had already reached the targets of YB/T108-97. The research on developing N6/Q235 clad plates was accomplished basically and successfully.
