Stainless steel surface processing grade:
Raw surface: NO.1 surface subjected to heat treatment and pickling after hot rolling.
Generally used for cold rolling materials, industrial tank tanks, chemical industrial equipment, etc., the thickness is from 2.0mm to 8.0mm.
Blunt surface: NO.2D cold rolled after heat treatment, pickling, its material is soft, the surface is silver-white luster, used for deep stamping processing, such as automobile components, water pipes, etc.
Fog surface: no.2b after cold rolling, heat treatment, pickling, and fine rolling to make the surface a moderate brightness.
Because the surface is smooth, easy to regrind, make the surface more bright, use extensively, such as tableware, building materials.
The surface treatment with improved mechanical properties satisfies almost all USES.
Coarse sand NO.3 products ground with NO. 100-120 abrasive belt.
With better gloss, with discontinuous coarse lines.
Used for interior and exterior decoration materials, electrical products and kitchen equipment, etc.
Fine sand: no.4 products ground with abrasive belt size 150-180.
With better gloss, with discontinuous coarse lines, stripes smaller than NO.3.
Used for decoration materials, electrical products, kitchen equipment and food equipment, etc.
Products ground with no. 320 abrasive belt.
With better gloss, with discontinuous coarse lines, stripes smaller than NO.4.
Used in bathhouses, interior and exterior decoration materials, electrical products, kitchen equipment and food equipment.
HAIRLINE: hlno.4 product with abrasive pattern (subdivided 150-320) produced by continuous grinding of polishing sand belt with appropriate granularity.
Mainly used for building decoration, elevator, doors, panels, etc.
Bright side: after cold rolling, BA is given a bright annealing, and after a smooth product.
The surface has excellent gloss and high reflectance.
It's like a mirror surface.
Used for household appliances, mirrors, kitchen equipment, decorative materials, etc.
