Stainless Steel 304L Surface Treatments and Characteristics
| Surface Finish | Characteristics and Application |
|---|---|
| NO.2B | The surface brightness and flatness of NO.2B is better than NO.2D. Through special surface treatment to improve mechanical properties, NO.2B satisfies comprehensive uses. |
| NO.1 | Surface finished by heat treatment and pickling or corresponding processes after hot rolling. |
| NO.4 | Polished with abrasive belt of grit #150-#180, has better brightness with discontinuous coarse striations. Used for bathtubs, building interiors/exteriors, electrical appliances, kitchen utensils, and food processing equipment. |
| HL | Polished with abrasive belt of grit #150-#320 on NO.4 finish with continuous streaks. Mainly used for building ornaments, elevators, building doors, and frontal plates. |
| BA | Cold rolled, bright annealed and skin-passed. Excellent brightness and good reflectivity like mirror. Used for kitchen apparatus and ornaments. |
| 8K | Excellent brightness and preferred 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 also 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
- Laboratory benches and equipment
- Rubber, plastics, pulp & paper machinery
- Pollution control equipment
- Boat fittings, valves and pump trim
