Application and good properties of 09CuPCrNi-A steel plate

09CuPCrNi-A steel plate belongs to weathering steel. By alloying with Cu, Mn, Si, Al, etc., and simply adjusting the element content of ordinary low carbon steel (Q235 steel), the 09CuPCrNi-A steel plate with good atmospheric corrosion resistance and comprehensive mechanical properties can be produced without changing the production process of Q235 steel. 09CuPCrNi-A steel plate is mainly used in railway, vehicle, bridge, tower and other steel structures exposed to the atmosphere for a long time.

09CuPCrNi-A steel plate is widely used in construction, bridge, shipbuilding, vehicle and other fields. The use environment of 09CuPCrNi-A steel plate is complex. Various requirements are put forward for the application of 09CuPCrNi-A steel plate. For example, the corrosion resistance of 09CuPCrNi-A steel plate is related to the corrosion resistance of railway vehicle, hull and offshore oil platform steel.
The service life of 09CuPCrNi-A steel plate is 8 times as long as that of ordinary steel without any anti-corrosion treatment, and it can be used for more than 30 years with antirust paint.
