| Abstract: | This paper introduces the development on 09CuPCrNi atmospheric corrosion resistant steel or railway vehicles. Better weldability and lower cost are obtained by adjusting the composition and controlling main alloy element content at a lower level. Steel strength is enhanced by appending strengthening microalloyed element . Steel cleanliness is improved by smelting in big , electric arc furnace and refining in ladle furnace. Finally,quality and mechanical properties of 09CuPCrNi atmospheric corrosion resisting steel developed achieve the new specification for railway vehicle. |
