1. Stainless Steel Sheet 304L 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 compreh ensive uses. |
| NO.1 |
The surface is finished by heat treatment and pickling or processes corresponding thereto after hot rolling. |
| 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. |
| HL |
Polished with abrasive belt of grit #150#320 on the NO.4 finish and has continuous streaks, 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. |

3. Resistance
Stainless steel's resistance to corrosion and staining, low maintenance and familiar lustre make it an ideal material for many applications.The alloy is used in cookware, cutlery, household hardware, surgical instruments, major appliances, industrial equipment and as an automotive and construction material in large buildings etc. It also can be use in commercial kitchens and food processing plants, as it can be steam-cleaned and sterilized and does not need paint or other surface finishes.
