Product Description
304 Stainless Steel Metal Sheet
Product Overview
ASTM A240 304 stainless steel sheet with various surface treatments for comprehensive industrial applications.
Surface Treatments & Characteristics
| Surface Finish | Characteristics and Application |
|---|---|
| NO.2B | Superior brightness and flatness compared to NO.2D, with enhanced mechanical properties for comprehensive uses |
| NO.1 | Heat treatment and pickling finish after hot rolling process |
| NO.4 | Polished with #150-#180 grit abrasive belt, featuring good brightness with discontinuous coarse striations. Used for bathtubs, building ornaments, electrical appliances, kitchen utensils, and food processing equipment |
| HL | Polished with #150-#320 grit on NO.4 finish, featuring continuous streaks. Ideal for building ornaments, elevators, doors, and frontal plates |
| BA | Cold rolled, bright annealed and skin-passed with excellent mirror-like brightness and reflexivity. Suitable for kitchen apparatus and decorative applications |
| 8K | Excellent brightness and superior mirror-like reflexivity |
