Characteristics and Applications |
| NO.2B |
Better brightness and flatness than NO.2D. Special surface treatment improves mechanical properties for comprehensive applications. |
| NO.1 |
Heat treatment and pickling after hot rolling process. |
| NO.4 |
Polished with abrasive belt grit #150-#180. Better brightness with discontinuous coarse striations. Used for bathtubs, building ornaments, appliances, kitchen utensils, and food processing equipment. |
| HL |
Polished with abrasive belt grit #150-#320 on NO.4 finish with continuous streaks. Used for building ornaments, elevators, doors, and frontal plates. |
| BA |
Cold rolled, bright annealed and skin-passed. Excellent brightness and mirror-like reflectivity for kitchen apparatus and ornaments. |
| 8K |
Excellent brightness and superior reflectivity, can be used as mirror. |

Corrosion Resistance
Stainless steel's resistance to corrosion and staining, low maintenance requirements, and familiar luster 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. It is particularly suitable for commercial kitchens and food processing plants, as it can be steam-cleaned and sterilized without requiring paint or other surface finishes.
Applications
- Food preparation equipment, especially in chloride environments
- Chemical processing equipment
