What is the chemical composition of 09CuPCrNi-A sheet?

09CuPCrNi-A is a atmospheric corrosion resistant steel plate. Chemical composition: C: 0.12 to 0.21, Si: 0.2 to 2.0, Mn: 0.7 to 2.0, S≤0.036, P≤0.034, Cu: 0.10 to 0.40, Al <0.2, and the rest are Fe and trace impurities. Through alloying of Cu, Mn, Si, Al, etc., and simple adjustment of some element content of ordinary low carbon steel (Q235 steel), it can produce good atmospheric corrosion resistance without changing the production process conditions of Q235 steel Economical weathering steel with comprehensive mechanical properties. 09CuPCrNi-A sheet is mainly used for steel structures such as railways, vehicles, bridges, and towers that have been exposed to the atmosphere for a long time.

 In recent years, the atmospheric corrosion resistant steel plate 09CuPCrNi-A is mainly used in railway vehicles, which can reduce the weight of the vehicle and extend the service life of the vehicle. Now the bridges, towers and garden landscapes that are gradually extending, especially after the launch of the Australian Pavilion of weather-resistant rust steel plates at the Shanghai World Expo. Weather-resistant steel sheets have been used by designers in landscape gardens, combined with flowers and trees, to rapidly enhance garden design effect, enhance economic and artistic benefits!
