Product Description
304 Stainless Steel Sheet Metal (SUS304 Mirror Finish)
Our 304 stainless steel sheets comply with ASTM A240 standards and are available in various surface finishes including 2B, mirror, and polished options.
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 treatment and pickling finish 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, creating 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-quality finish. |
