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
