Stainless steel with different surface treatment processes
Time:2019-10-29 Source: Hits:

Stainless steel surface treatment is to form a special surface layer on the surface by physical or chemical means, which can change the appearance, texture and function of stainless steel.

What is the common surface treatment technology that is implemented in those areas?

Stainless steel surface treatment


The surface after heat treatment and pickling treatment after NO.1 hot rolling.
Generally used for cold-rolled materials, industrial tanks, chemical industrial equipment, etc., stainless steel processing thickness is 2.0MM-8.0MM.

Blunt surface:

After cold rolling, NO.2D is heat treated and pickled. The material is soft and the surface is silvery white.
Used for deep drawing processing, such as automotive components, water pipes, etc.


After cold rolling, NO.2B is subjected to heat treatment, pickling, and then finish rolling to make the surface moderately bright.
Because the surface is smooth, it is easy to re-grind, making the surface brighter and widely used, such as tableware and building materials.

coarse sand

NO.3 is a product ground with a 100-120 grinding belt. It has better gloss and has discontinuous rough lines.
Used in interior and exterior decorative materials, electrical products and kitchen equipment.

Fine sand:

NO.4 is a product ground with a grinding belt of size 150-180. It has better gloss, has discontinuous rough lines, and is thinner than NO.3.
Used in baths, interior and exterior decoration materials, electrical products, kitchen equipment and food equipment.

Hairline HAIRLINE:

HLNO.4 produces a ground pattern product (subdivided from No. 150-320) by continuous grinding of a suitable size abrasive belt.
Mainly used for architectural decoration, elevators, building doors, panels, etc.


After the cold rolling of BA, the product is subjected to bright annealing and flattened. The surface gloss is excellent and has a high reflectivity. Like a mirrored surface.
Used in home appliances, mirrors, kitchen equipment, decorative materials, etc.

Stainless steel surface processing grade industry process has formed a standard, zibo Baishun stainless steel Chinese manufacturer has deep research on the surface treatment process of stainless steel, has been skilled in stainless steel
The surface treatment technology, and the overseas customers we cooperate with are satisfied with our stainless steel products, and the customers are definitely the driving force for our continued production of stainless steel.
