What is 09CuPCrNiA corten steel plate

09CuPCrNiA corten steel plate is mild steel with rusty appearance. 09CuPCrNiA corten steel plate is so-called self-adhesive steel to which have been added a number of alloys such as copper, chromium, nickel and molybdenum, to increase its resistance to atmospheric corrosion.

09CuPCrNiA corten steel plate is weather resistant steel created by alloying copper, chromium and nickel. 09CuPCrNiA corten steel plate also has added phosphorous which makes it best suited for gas flue applications and for aesthetic facias.

09CuPCrNiA corten steel plate naturally forms a layer of rust or patina when exposed to various atmospheric conditions. This patina is what guards 09CuPCrNiA corten steel plate against future corrosion.
