Original surface: 

NO.1 surface treated with heat treatment and pickling after hot rolling. Generally used for cold-rolled materials, industrial tanks, chemical industrial equipment, etc., the thickness is thicker from 2.0MM to 8.0MM. The stainless steel pipe processing plant also has a matte surface. 

After NO.2B cold rolling, it is heat-treated, pickled, and then finished rolling to make the surface moderately bright. Because the surface is smooth and easy to re-grind, it makes the surface brighter and has a wide range of uses, such as tableware, building materials, etc. After adopting the surface treatment to improve the mechanical properties, it can meet almost all purposes.

Blunt surface: 

No.2D cold-rolled after heat treatment and pickling, its material is soft, the surface is silver-white luster, used for deep drawing processing, such as automotive components, water pipes, etc. Coarse sand NO.3 is a product grinded with a No. 100-120 grinding belt. It has better gloss and discontinuous rough lines. Used in building interior and exterior decoration materials, electrical products and kitchen equipment, etc. Fine sand is also a surface finishing grade product often produced by stainless steel pipe processing plants.

In addition to the above divisions, there are many other surface grades of stainless steel pipe products produced by stainless steel pipe processing plants. The bright surface is a kind of special surface brightness, which can be directly used to make mirrors or other decorative products. It is beautiful and can maintain brightness for a long time without worrying about corrosion. The specific surface processing grade should be selected according to the characteristics of the product, to be as beautiful and practical as possible.
