CR Coils, for Industrial

Listing ID #7075249

Cold rolled steel coil (CR coil) is essentially hot-rolled steel. After the scale is removed by pickling, it is continuously cooled at room temperature and then annealed and temper-rolled. During continuous cold rolling, the strength and hardness of the hard rolled coil increase, and the ductility and plasticity decrease. Also, the steel coil is with tighter dimensional tolerances and better surface finishes.
