Product Detail

The surface processing of stainless steel sheet have NO.1, 2B, No. 4, HL, No.
6, No. 8, BA, TR hard, Rerolled bright 2H, polishing bright and other surface
finishes, etc.

NO.1: No. 1 surface refers to the surface obtained by heat treatment and
pickling after hot rolling of the stainless steel sheet. It is to remove the
black oxide scale produced during hot rolling and heat treatment by pickling or
similar treatment methods. This is No. 1 surface processing. The No.1 surface is
silvery white and matt. Mainly used in heat-resistant and corrosion-resistant
industries that do not require surface gloss, such as alcohol industry, chemical
industry and large containers.

2B: The surface of 2B is different from the 2D surface in that it is smoothed
with a smooth roller, so it is brighter than the 2D surface. The surface
roughness Ra value measured by the instrument is 0.1～0.5μm, which is the most
common processing type. This kind of stainless steel sheet surface is the most
versatile, suitable for general purposes, which is widely used in the chemical,
paper, petroleum, medical and other industries, and can also be used as a
building curtain wall.

TR Hard Finish: TR stainless steel is also called hard steel. Its
representative steel grades are 304 and 301, they are used for products that
require high strength and hardness, such as railway vehicles, conveyor belts,
springs and gaskets. The principle is to use the work hardening characteristics
of austenitic stainless steel to increase the strength and hardness of the steel
plate by cold working methods such as rolling. The hard material uses a few
percent to several tens of percent of the mild rolling to replace the mild
flatness of the 2B base surface, and no annealing is carried out after rolling.
Therefore, the TR hard surface of the hard material is the rolled after cold
rolling surface.

Rerolled Bright 2H: After the rolling process. the stainless steel sheet will
be processed bright annealing. The strip can be fast cooled by the the
continuous annealing line. The traveling speed of the stainless steel sheet on
the line is around 60m~80m/min. After this step, the surface finish will be 2H
rerolled bright.

No.4: The surface of No. 4 is a fine polished surface finish that is brighter
than the surface of No. 3. It is also obtained by polishing the stainless steel
cold-rolled stainless steel plate with 2 D or 2 B surface as the base and
polishing with abrasive belt with a grain size of 150-180# Machined surface. The
surface roughness Ra value measured by the instrument is 0.2～1.5μm. NO.4 surface
is widely used in restaurant and kitchen equipment, medical equipment,
architectural decoration, containers, etc.

HL: HL surface is commonly called hairline finish. Japanese JIS standard
stipulates that 150-240# abrasive belt is used to polish the continuous
hairline-like abrasive surface obtained. In China’s GB3280 standard, the
regulations are rather vague. HL surface finish is mostly used for building
decoration such as elevators, escalators, and facades.

No.6: The surface of No. 6 is based on the surface of No. 4 and is further
polished with a Tampico brush or abrasive material with a particle size of W63
specified by GB2477 standard. This surface has a good metallic luster and soft
performance. The reflection is weak and does not reflect the image. Due to this
good property, it is very suitable for making building curtain walls and
building fringe decorations, and also widely used as kitchen utensils.

BA: BA is the surface obtained by bright heat treatment after cold rolling.
Bright heat treatment is annealing under a protective atmosphere that guarantees
that the surface is not oxidized to preserve the gloss of the cold-rolled
surface, and then use a high-precision smoothing roll for light leveling to
improve the surface brightness. This surface is close to a mirror finish, and
the surface roughness Ra value measured by the instrument is 0.05-0.1μm. BA
surface has a wide range of uses and can be used as kitchen utensils, household
appliances, medical equipment, auto parts and decorations.

No.8: No.8 is a mirror-finished surface with the highest reflectivity without
abrasive grains. The stainless steel deep processing industry also calls as 8K
plates. Generally, BA materials are used as raw materials for mirror finishing
only through grinding and polishing. After mirror finishing, the surface is
artistic, so it is mostly used in building entrance decoration and interior
decoration.
