| Surface | Description |
| Plug Draw | The surface roughness is improved by precise cold drawing of the plug, which can improve the surface structure |
| Mechanically Polished | Surface roughness enhanced by precision grinding |
| Pickled & Passivated | Pickled or passivated to remove particles remaining on the surface |
| Buffed Polished | use polishing paste to improve surface brightness, often used in decoration industry |
| Bright Annealing | Use high temperature heat treatment in a vacuum state to form a passivation film on the surface |
| Anodical Cleaning | On the basis of BA, add a mild electrolytic polishing process and thicken the passivation film |
| Electro-Polished | Through electrochemical polishing, the surface has a closed and thick chromium oxide film |
