Product description
Precision strip steel can be graded for precision control, it pays
attention to the quality of stability, high precision, as well as
mechanical and mechanical performance in the high precision
requirements. Internationally, its thickness accuracy requires the
difference between positive and negative not more than 1 micron,
the width accuracy requires the difference between positive and
negative not more than 0.1mm, the surface quality to meet the needs
of different users, such as the roughness of Ra .0.16mm 2B surface,
roughness Ra .05mm BA surface or other special surface; General
control is 7.0-9.0, for hard-state products, the strength
performance should be uniform, hardness fluctuations between
5-10Hv.
In addition, the straightness, edge quality and other aspects have
higher requirements.

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. |
