Product Description
SA240/SA240m Type 304L Stainless Steel Plate
Hot Finished in Solution Annealed Pickled and Passivated No. 1 Finished
Product Overview
SA240/SA240M Type 304L Stainless Steel Plate Hot Finished in Solution Annealed Pickled and Passivated NO.1 Finished
Surface Treatment Characteristics
| Surface Finish | Characteristics and Application |
|---|---|
| NO.2B | Better surface brightness and flatness than NO.2D. Special surface treatment improves mechanical properties, suitable 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 mirror-like reflexivity for kitchen apparatus and ornaments. |
| 8K | Excellent brightness and superior mirror-like reflexivity. |
