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.
