Product Description
ASTM A240 304 Stainless Steel Sheet
Our 304 stainless steel sheets comply with ASTM A240 standards and are available in various surface finishes to meet diverse industrial requirements.
Surface Treatment Options
| Surface Finish | Characteristics and Applications |
|---|---|
| NO.2B | Superior brightness and flatness compared to NO.2D, with enhanced mechanical properties through special surface treatment. Suitable for comprehensive applications. |
| NO.1 | Heat-treated and pickled surface after hot rolling process. |
| NO.4 | Polished with #150-#180 grit abrasive belt, featuring good brightness with discontinuous coarse striations. Ideal for bathtubs, building ornaments, appliances, kitchen utensils, and food processing equipment. |
| HL | Polished with #150-#320 grit abrasive belt on NO.4 finish, producing continuous streaks. Primarily used for building decorations, elevators, doors, and frontal plates. |
| BA | Cold rolled, bright annealed, and skin-passed for excellent brightness and mirror-like reflectivity. Perfect for kitchen apparatus and decorative applications. |
| 8K | Exceptional brightness and superior reflectivity, achieving mirror-like quality. |

Corrosion Resistance
Stainless steel's exceptional resistance to corrosion and staining, combined with low maintenance requirements and attractive appearance, makes it ideal for numerous applications. This 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
