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.
