Cold Rolled Carbon Steel Coil

Cold rolling is rolling under recrystallization, but it is generally understood as rolling using normal temperature rolling materials. Since cold-rolled coils are not heated during the production process, there are no defects such as pitting and scale that often occur in hot rolling, and the surface quality is good and the finish is high. Moreover, the dimensional accuracy of cold-rolled products is high, and the performance and structure of the products can meet some special requirements for use, such as electromagnetic properties and deep drawing properties.

The difference between chilled coil and cold rolled coil:

Chilled coils are hot-rolled coils that are pickled and cold-rolled. It can be said to be a kind of cold rolled coil.

Cold-rolled coils (annealed state): hot-rolled coils obtained by pickling, cold rolling, bell annealing, tempering, and (finishing).

There are three main differences between the two:

1. In appearance, generally chilled coils are a bit black.

2. The surface quality, structure, and dimensional accuracy of cold-rolled sheets are better than chilled coiled sheets.

3. In terms of performance, because the chilled coil directly obtained by the hot-rolled coil through the cold rolling process undergoes work hardening during cold rolling, resulting in an increase in yield strength and residual internal stress, the external performance is relatively "hard". It is called chilled coil.

Therefore, the yield strength: the chilled coil is larger than the cold-rolled coil (annealed state), which makes the cold-rolled coil (annealed state) more conducive to stamping.

Generally, the default delivery state of cold-rolled coils is annealed.
