Original surface: NO.1 surface treated with heat treatment and pickling after hot rolling. GENERALLY USED IN COLD-ROLLED MATERIALS, INDUSTRIAL TANKS, CHEMICAL INDUSTRIAL EQUIPMENT, ETC., THE THICKNESS IS THICKER FROM 2.0MM-8.0MM. Stainless steel pipe processing plant also has a matte surface, NO.2B cold rolling after heat treatment, pickling, and then finishing processing to make the surface moderately bright. Because the surface is smooth, it is easy to regrind, making the surface more shiny, and it is widely used, such as tableware, building materials, etc. With a surface treatment with improved mechanical properties, it can meet almost all applications.
Blunt surface: NO.2D after cold rolling after heat treatment, pickling, its material is soft, the surface is silvery-white luster, used for deep drawing processing, such as automobile components, water pipes, etc. Coarse sand NO.3 is a product ground out of 100-120 grinding tape. It has a better gloss with discontinuous coarse lines. Used in building interior and exterior decoration materials, electrical products and kitchen equipment. Fine sand is also a surface processing grade that is often produced by stainless steel pipe processing plants.
In addition to the above division, there are many other surface grades of stainless steel pipe products produced by stainless steel pipe processing plants. Glossy surface is a kind of surface brightness special kind, can be directly used to make mirrors, or other decorative products, etc., beautiful and generous, but also can maintain brightness for a long time, without worrying about corrosion. What kind of surface processing grade should be selected, but also need to be selected according to the characteristics of the product, as far as possible to be beautiful and practical.
