Stainless
steel can be seen everywhere in life, use very extensive. Recently, the price for stainless steel is up and down. We feel so tired about it. Leave it alone for a moment. Today let’s learn
about the surface of stainless steel grades, characteristics and uses.
Original
surface
Stainless
steel NO.1, it is surface after the hot rolled annealed and pickled. Hot-rolled
stainless steel NO.1 generally used to make cold rolled stainless steel
material, industrial tanks, chemical plant, etc., the thickness from
3.0MM-16.0MM.
Blunt
surface
Stainless
steel NO.2D, it is surface that after cold rolling then heat treatment,
pickling. Its material is soft, with silvery sheen color. It is used for deep
drawing processing, such as automobile parts, water pipes and so on.
Matte
Surface
Stainless
steel NO.2B.It is surface that after cold rolling and heat treatment, pickling,
and then polish to make the surface moderate light. Since the surface is
smooth, it is easy to regrind, make surface more brighter. It is widely used,
such as utensils, building materials and so on. Using improve the mechanical
properties of the surface treatment, it can meet almost all uses.
Grit
Surface
Stainless
steel NO.3.It uses No. 100-120 abrasive belt to grind out product. It has
better brightness with discontinuous coarse grain. It is used for interior and
exterior building materials, electrical appliances and kitchen equipment.
Sand
surface
Stainless
Steel NO.4. It is abrasive grain size No. 150-180 abrasive belt out of the
product. It has better brightness, and discontinuous coarse grain, fine stripes
than NO.3. It is used for baths, interior and exterior building materials,
electrical appliances, kitchen equipment and food equipment.
Bristle
surface HAIRLINE
Stainless
HL / NO.4. It is a continuous grinding belt properly size generating abrasive
polishing pattern product (segment number 150 to 320). Mainly used for building
decoration, elevators, building door panels.
Bright
Surface
Stainless
steel BA. It is subjected to bright annealing after cold rolling, and after
formation of the resulting product. Its excellent surface gloss, has a high
reflectivity. It is like a mirror surface for home appliances, mirrors, kitchen
equipment, decorative materials.
CNBM is the short name of China
National Building Material Group, which is a state-own group. We
specialized in steel products, especially stainless steel products.
