Stainless Steel Surface Treatments
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 Machining —is in a mirror state. Processing technology: 2D
or 2B products are ground and polished to a mirror effect with a
suitable abrasive material.
| Surface Finish | Definition | Application |
| 2B | Those finished, after cold rolling, by heat treatment, pickling or other equivalent treatment and lastly by cold rolling to given appropriate luster. | Medical equipment, Food industry, Construction material, Kitchen utensils. |
| BA | Those processed with bright heat treatment after cold rolling. | Kitchen utensils, Electric equipment, Building construction. |
| NO.3 | Those finished by polishing with No.100 to No.120 abrasives specified in JIS R6001. | Kitchen utensils, Building construction. |
| NO.4 | Those finished by polishing with No.150 to No.180 abrasives specified in JIS R6001. | Kitchen utensils, Building construction, Medical equipment. |
| HL | Those finished polishing so as to give continuous polishing streaks by using abrasive of suitable grain size. | Building construction |
| NO.1 | The surface finished by heat treatment and pickling or processes corresponding there to after hot rolling. | Chemical tank, pipe. |
