Product Description
304 Stainless Steel Metal Sheet (SUS304)
ASTM A240 304 stainless steel sheet with various surface treatments for comprehensive industrial applications.
Surface Treatments and Characteristics
| Surface Finish | Characteristics and Application |
|---|---|
| NO.2B | Better brightness and flatness than NO.2D. Special surface treatment improves mechanical properties 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 good mirror-like reflexivity. Used 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, and familiar luster make it ideal for many applications. The alloy is used in cookware, cutlery, household hardware, surgical instruments, major appliances, industrial equipment, and as automotive and construction material in large buildings. It can be used in commercial kitchens and food processing plants as it can be steam-cleaned and sterilized without needing 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
