Product Description
304 Stainless Steel Mirror Sheet - 8K Finish
High-quality ASTM A240 304 stainless steel sheets with various surface treatments including 2B, BA, and premium 8K mirror finish.
Surface Treatments & Characteristics
| Surface Finish | Characteristics and Applications |
|---|---|
| NO.2B | Superior brightness and flatness compared to NO.2D. Enhanced mechanical properties through special surface treatment for comprehensive applications. |
| NO.1 | Heat treatment and pickling finish after hot rolling process. |
| NO.4 | Polished with #150-#180 grit abrasive belt. Features better brightness with discontinuous coarse striations. Used for bathtubs, building ornaments, appliances, kitchen utensils, and food processing equipment. |
| HL | Polished with #150-#320 grit on NO.4 finish with continuous streaks. Ideal for building decorations, elevators, doors, and frontal plates. |
| BA | Cold rolled, bright annealed, and skin-passed. Excellent brightness and mirror-like reflectivity for kitchen apparatus and decorative applications. |
| 8K | Premium mirror finish with exceptional brightness and superior reflectivity for high-end applications. |
