The main raw material of 09CuPCrNi-A steel hardness, hot rolling coil is billet. After heating the billet, the strip made from the coarse and fine rolling mill is cooled to a certain temperature by specific cooling, and then the cooled steel strip is made into rolled steel strip by coiler. But generally, according to the buyer's demand, the manufacturer can further process the cooled steel strip into steel plate or flat coil and other products.
