Surface Treatment and characteristic
| Surface finish | Characteristics and application |
| NO.2B | The surface brightness and flatness of no2B is better than no2D. then through a special surface |
| treatment to improve its mechanical properties,No2B could nearly satisfy | |
| comprehensive uses. | |
| The surface is finished by heat treatment and pickling or processes corresponding thereto after hot rolling. | |
| NO.1 | |
| NO.4 | Polished with abrasive belt of grit #150-#180,have better brightness with discontinuous |
| coarse stria,but thinner than No3, are used as bathtub buildings inner and external | |
| ornaments electrical appliances kitchen utensils and food processing equipment etc. | |
| Polished with abrasive belt of grit #150-#320 on the NO.4 finish and has continuous streak | |
| HL | mainly used as buildings ornaments elevators,door of building, frontal plate etc. |
| BA | Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good |
| reflexivity like mirror,kitchen apparatus,ornament etc. | |
| 8K | The product have excellent brightness and prefer reflexivity can to be the mirror. |
No 1 Finish
Plate is hot rolled, annealed, pickled and passivated. This results in a dull, slightly rough surface; quite suitable for industrial applications which generally involve the range of plate thicknesses. Grinding marks may be visible in isolated areas.
Some of the thinner thicknesses within the plate range are Cold Rolled; but Sheet, Coil and Strip gauges are produced by Cold Rolling, ie rolled without and heating of the material. Cold Rolling hardens the material, and the thinner sizes may have to be subjected to an intermediate anneal and pickle, or bright annealed, during the reduction of thickness to final gauge.
The starting material for Cold Rolling always has a No. 1 finish. Cold Rolled material is supplied with the following standard mill finishes.
No. 3 Finish
This is a ground unidirectional uniform finish obtained with 80 - 100 grit abrasive.
It is a good intermediate or starting surface finish for use in such instances where the surface will require further polishing operations to a finer finish after subsequent fabrication or forming.
No. 4 Finish
This is a ground unidirectional finish obtained with 150 grit abrasive. It is not highly reflective, but is a good general purpose finish on components which will suffer from fairly rough handling in service (eg restaurant equipment).
No. 6 Finish
These finishes are produced using rotating cloth mops (Tampico fibre, muslin or linen) which are loaded with abrasive paste.
The finish depends on how fine and abrasive is used, the uniformity and finish of the original surface.
The finish has a non-directional texture of varying reflectiveness. "Satin Blend" is an example of such a finish.
No. 7 Finish
This is a buffed finish having a high degree of reflectiveness.
It is produced by progressively using finer and finer abrasives and finishing with Buffing compounds. Some fine scratches (grit lines) may remain from the original starting surface.
No. 8 Finish
This is produced in an equivalent manner to a No. 7 Finish, the final operations being done with extremely fine buffing compounds.
The final surface is blemish free with a high degree of image clarity, and is the true mirror finish.
Note
The finer polished finishes (No. 4, No. 6, No. 7 and No. 8) are generally only produced one side of the sheet, the reverse side being either a 2B or No. 3 Finish.
