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. 2D
A smooth, non-reflective cold-rolled annealed and pickled or descaled finish. This non-directional finish is favourable for the retention of lubricants in deep drawing applications.
2B
2B is the most widely used stainless steel surface finish. It is especially common in industrial, chemical and food processing applications such as process vessels and tanks. It is also used in some architectural applications that will not be closely examined for uniformity of finish such as downpipes and gutters.
When specifying this finish think about these attributes:
- 2B is the most economical finish
- it is highly corrosion resistant because it has been chemically pickled and is smooth
- over broad areas and between batches, etc it is not uniform and may not match in appearance
- it has been produced in the mill and can't be matched after fabrication
- it is often protected by plastic films until final cleanup and commissioning
Bright Annealed (BA)
The classic use of a BA finish is domestic: the interior of a dishwasher or clothes washing machine. In the clothes washer, it also provides a smooth, non-abrasive surface for the clothes to slide around. The mirror like surface is also used in road mirrors where a precise image is not required.
When specifying this finish think about these attributes:
- BA is common in some grades and thicknesses, but not all
- it is highly corrosion resistant because it is very smooth
- different batches may not match
- it has been produced in the mill and can't be exactly matched after fabrication although a mechanical mirror polish can be close.
