18 Gauge Cold Rolled Sheet Metal Steel Plate Cold Rolled Steel Sheet

The Difference Between Cold-Rolled Steel Coil And Hot-Rolled Steel:

1. Appearance and surface quality: Cold-rolled steel coil is better in surface quality (such as Surface roughness) than hot plate because it is obtained by cold rolling and some surface finishing is carried out at the same time. Therefore, if the product after the sequence of painting, such as coating quality, there are higher requirements, the general choice of the cold plate. The hot plate is divided into the pickling plate and the unpickling plate. The surface of the pickling plate becomes the normal metal color because of pickling, but the surface of the unsold-rolled plate is not as high as that of the cold-rolled plate, or the existence of ferrosoferric oxide layer, colloquially it is fire-roasted, and if the storage environment is not good, usually with a little embroidery.

2. Properties: In general, the Mechanical Properties of hot and cold-rolled steel coil are considered to be the same in engineering, although there is a certain amount of work hardening during cold rolling, (but not rule out the case of strict mechanical performance requirements, it needs to be treated differently), cold-rolled steel coil usually than hot plate yield strength slightly higher, surface hardness is also higher, how specific need to see cold plate annealing degree. However, the strength of the annealed plate is higher than that of the hot plate.

3. Forming performance: Because the performance of cold and hot-rolled steel coil is basically not too much, so the forming performance of the influence factor depends on the difference of its surface quality, because the surface quality is the cold-rolled steel coil to be better, so generally speaking the same material steel plate, the appearance of cold plate is better than that of the hot plate.
