Stainless Steel Surface

1D — The surface has discontinuous granular shape, also known as fog surface.

Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.

2D – A slightly silvery white colour.

Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.

2B — Silver white with better gloss and flatness than a 2D surface.

Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling.

Ba – Excellent surface gloss, high reflectivity, like a mirror surface.

Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenching and tempering rolling.

No.3 — Good gloss, coarse grain surface.

Processing technology: 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.

Processing technology: 2D products or 2B products with appropriate granularity of abrasive materials for polishing the surface is a continuous abrasive grain.

MIRRO — Specular.

Processing technology: 2D products or 2B products with appropriate granularity of the grinding material grinding and polishing to the mirror effect.
