Summary of manufacturing method |
use |
NO.1 |
Silver white matt |
Hot rolled to the specified thickness, on a rough, matte surface that has been annealed and dephosphorized |
No need for surface gloss purposes |
NO.2D |
silver white |
After cold rolling, heat treatment and pickling are carried out, and sometimes the matte surface is processed by the final light rolling on the rough surface. |
2D products are used for applications that do not require strict surface requirements, general materials, and deep drawing materials |
NO.2B |
Stronger gloss than NO.2D |
After NO.2D treatment, the polished roller is used for the final light cold rolling to obtain a suitable gloss. This is the most commonly used surface processing, and this processing can also be used as the first step of polishing |
General materials |
BA |
Bright as a mirror |
There is no standard, but it is usually bright annealed surface processing, with high surface reflectivity |
Building materials, kitchen utensils |
NO.3 |
Rough grinding |
Grind NO.2D and NO.2B materials with 100~200# (unit) grinding belts |
Building materials, kitchen utensils |
NO.4 |
Intermediate grinding |
The polished surface obtained by grinding NO.2D and NO.2B materials with 150~180# stone abrasive belts. This is a general purpose, with a mirror-reflected bright surface with visible "grains" |
Same as above |
