304L Stainless Steel Sheet - 1.5m × 3m × 6mm
ASTM A240 304L stainless steel sheet with various surface finishes for comprehensive industrial applications.
Surface Treatments & Characteristics
| Surface Finish |
Characteristics and Application |
| NO.2B |
Better brightness and flatness than NO.2D. Special surface treatment improves mechanical properties, suitable for comprehensive uses. |
| NO.1 |
Surface finished by heat treatment and pickling after hot rolling. |
| 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 reflexivity for kitchen apparatus and ornaments. |
| 8K |
Excellent brightness and preferred reflexivity, can be used as mirror. |

Corrosion Resistance
Stainless steel's resistance to corrosion and staining, low maintenance requirements, and familiar luster make it ideal for numerous applications. The alloy is used in cookware, cutlery, household hardware, surgical instruments, major appliances, industrial equipment, and as construction material in large buildings. It's 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
