| Bright Annealed | Black Annealed |
|---|---|
| The biggest difference between black regression and heating is that it is not in contact with the air, with nitrogen and other inert gases have been protected, the surface color is maintained and the same as cold rolled strip steel, in addition to the use of black regression is also used for surface tinning and other surface treatment, beautiful and generous. | The cold rolled strip is heated directly to the annealing temperature, and the surface color turns black due to high temperature contact with air. The physical properties become soft, and it is generally used for steel strip repressing, stamping, and deep processing with large deformation. |
