| Surface Finish of stainless steel coil | |
| Surface Finish | Definition and Application |
| No.1 | The surface is finished by heat treatment and pickling or processes corresponding theretoafter hot rolling |
| 2D | The finishes after cold rolling, by heat treatment, pickling or other equivalenttreatment |
| 2B | The finish after cold rolling, by heat treatment, pickling or other equivalent treatment and lastly by cold rolling to give an appropriate luster |
| BA | Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror |
| NO.3 | Polished with abrasive belt of grit#100~#200,have better brightness with discontinuous coarse stria |
| NO.4 | Polished with abrasive belt of grit#150~#180,have better brightness with discontinuous coarse stria |
| HL | Polished with abrasive belt of grit#150~#320 on the NO.4 finish and has continuous streaks |
| 8K | The product have excellent brightness and prefect reflexivity can be the mirror |
