Surface
1D—The surface has discontinuous particles, which is also called matte. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2D—Slightly shiny silver-white. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2B—Silver white and better gloss and flatness than 2D surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling.
BA—The surface gloss is excellent and has a high reflectivity, just like the mirror surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenched and tempered rolling.
No.3—has better gloss and rough surface. Processing technology: Polishing and tempering rolling of 2D products or 2B with 100 ~ 120 abrasive materials.
No.4—has better gloss and fine lines on the surface. Processing technology: Polishing and tempering rolling of 2D products or 2B with 150 ~ 180 abrasive materials.
HL—Silver gray with hair streaks. Processing technology: Polish the 2D product or 2B product with a suitable size of abrasive material to make the surface appear continuous grain.
MIRROR—is in a mirror state. Processing technology: 2D or 2B products are ground and polished to a mirror effect with a suitable abrasive material.
