High Strength Blue Black Iron Clad Mild Low Carbon Spring Steel Coil
Product Information of Cold-rolled Sheet
Cold-rolled sheet in coil form is produced by removing rust from hot-rolled sheet by „pickling“ it in a weak acid solution, then washing, brushing, drying, oiling and unrolling the sheet and finally performing cold-rolling by passing the sheet through a reducing mill under pressure and winding it into a roll.
Carbon steel coil is mainly used for manufacturing complex shape, high mechanical performance requirements, but in the process and it is difficult to use forging and pressing methods to form the more important mechanical parts, such as automobile gearbox housing, locomotive and vehicle couplings and so on.
