Finish |
Characteristics |
Application |
|
No.1 |
Hot rolled to the specified thickness, appear with a rough/matte surface after annealing and de rolling |
Applications that do not require surface gloss |
|
2D |
After cold rolling, heat treatment and acid washing are carried out, and sometimes the final light rolling is carried out on the rough surface roller, which is a matte surface processing |
Materials used for applications with less stringent surface requirements, deep drawing materials |
|
2B |
After 2D processing, polished silver is used for the final light cold rolling to achieve a suitable gloss. This is the most commonly used surface processing, which can also be used as the first step in polishing |
General usage |
|
BA |
Surface processing without standards but usually with bright annealing, with high surface reflectivity |
Construction material, kitchen ware |
|
No.3 |
Grind NO.2D and NO.2B materials with 100-200# (unit of smashing grinding tape) |
Construction material, kitchen ware |
|
No.4 |
The polished surface obtained by grinding NO.2D and NO.2B materials with a 150~180 # abrasive belt is a universal mirror reflective bright surface with visible grains |
Construction material, kitchen ware |
