Product Description
AISI 304 Sheet 3X1500X3000 mm Surface 2b Without Foil
304 stainless steel sheet manufactured according to ASTM A240 standards with 2B surface finish.
Surface Treatment Options
| Surface Finish | Characteristics and Applications |
|---|---|
| NO.2B | Superior surface brightness and flatness compared to NO.2D. Enhanced mechanical properties through special surface treatment, suitable for comprehensive applications. |
| NO.1 | Heat treatment and pickling finish after hot rolling process. |
| NO.4 | Polished with #150-#180 grit abrasive belt, providing good brightness with discontinuous coarse striations. Used for bathtubs, building ornaments, appliances, kitchen utensils, and food processing equipment. |
| HL | Polished with #150-#320 grit abrasive belt on NO.4 finish, featuring continuous streaks. Primarily used for building ornaments, elevators, doors, and frontal plates. |
| BA | Cold rolled, bright annealed and skin-passed. Excellent brightness and mirror-like reflectivity. Ideal for kitchen apparatus and decorative applications. |
| 8K | Excellent brightness and superior mirror-like reflectivity. |

Corrosion Resistance
Stainless steel's excellent resistance to corrosion and staining, combined with low maintenance requirements and attractive appearance, make it ideal for numerous applications. The alloy is widely used in cookware, cutlery, household hardware, surgical instruments, major appliances, industrial equipment, and automotive and construction components for 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
- Laboratory benches and equipment
- Rubber, plastics, pulp & paper machinery
- Pollution control equipment
- Boat fittings, valves and pump trim
