What is the difference between 09CuPCrNi-A and corten steel plates

As the quality and price advantages of China steel becomes more outstanding, Chinese corten steel GB/T 1979 09CuPCrNi-A corten steel plates are becoming popular on the International market, and also widely used in the Middle East, South Asia. etc regions. Many foreign clients that need ASTM corten A or corten B steel plates also consider to use 09CuPCrNi-A steel instead to pursue higher cost efficiency and shorter delivery time.

In order to help the clients to make decision, we would like to share the common points and difference between 09CuPCrNi-A and corten steel plates with you.

1. The common points and difference between 09CuPCrNi-A and corten steel plates in chemical composition:

We can see there is only very small difference between 09CuPCrNi-A and corten steel plates. The only point need attention is Cr content. As 09CuPCrNi-A steel can cover 0.30-0.50 Cr also, which can not reach requirement of corten A or corten B steel. But the Cr content of 09CuPCrNi-A steel can also be 0.50-1.25, so it is better to confirm with 09CuPCrNi-A steel plates supplier when arrange purchasement if you care Cr content much.

2. The common points and difference between 09CuPCrNi-A and corten steel plates in mechanical properties:

From the data, the strength of ASTM corten steel seems higher than that of GB/T 1979 09CuPCrNi-A corten steel plates. But in actual condition, 09CuPCrNi-A steel plates usually can well meet the strength requirements of corten steel also. And 09CuPCrNi-A steel has better price, smaller MOQ and faster delivery. That is why many clients prefer to choose GB/T 1979 09CuPCrNi-A corten steel plates other than ASTM corten A or corten B steel plates at last.
