309 Stainless Steel Processing Technology
| Surface | Features | Processing technology |
|---|---|---|
| 1D | The surface has a discontinuous granular shape known as a fog surface. | hot rolling + annealing shot peening pickling + cold rolling + annealing pickling. |
| 2D | A slightly silvery white color. | hot rolling + annealing shot peening pickling + cold rolling + annealing pickling. |
| 2B | Silver white with better gloss and flatness than a 2D surface. | hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling. |
| Ba | Excellent surface gloss, high reflectivity, like a mirror surface. | hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenching and tempering rolling. |
| No.3 | Good gloss, coarse grain surface. | polishing and tempering rolling for 2D or 2B with 100~120 abrasive materials (JIS R6002). |
| No.4 | Good gloss, fine lines on the surface. | Processing process: polishing and tempering rolling for 2D or 2B with 150~180 abrasive materials (JIS R6002). |
| HL | Silver grey with hair streaks. | 2D products or 2B products with the appropriate granularity of abrasive materials for polishing continuous abrasive grains surface. |
| MIRRO | Specular. | 2D products or 2B products with appropriate granularity of the grinding material grinding and polishing to the mirror effect. |
