Products Description
In the grade of CR4 cold-rolled coil, "C" stands for cold rolling, "R" stands for the rolling process, and "4" stands for the carbon content of the steel, which is about 0.08%. Compared with CR1, CR2, and CR3 steel, CR4 steel coil has a lower carbon content and is more widely applicable.
During the cold rolling process, CR4 cold-rolled galvanized steel coil undergoes multiple rolling, annealing and other process treatments, has good plasticity and is easy to process and shape. After deburring, pickling and other treatments, the surface is flat and smooth, without obvious scratches or rust. After the process treatment, its crystal structure is compact, forming fine grains, and has good strength in the internal structure.
