The paper discusses the importance of enhancing ductility of ship-building plates and clarifies the fundamental methods of increasing ductility while remains the relatively higher strength： decreasing content of carbon,purifying the steel products during melting,refinement,uniformity and inclusion modified,etc.Finally,the newly developed refinement method RPC（relaxation-precipitation-transformation control） is introduced.
