The surface processing method of stainless steel pipe

When purchasing stainless steel pipes, we are often overwhelmed by the surface conditions of stainless steel pipes. Is the original surface better or the dull surface better? Let's take a look at the processing methods of these two surfaces, which may inspire you a little differently.

Original surface: No.1 surface that is subjected to heat treatment and pickling after hot rolling. Generally used for cold-rolled materials, industrial tanks, chemical industry equipment, etc., the thickness is thicker from 2.0MM-8.0MM. There are also matte stainless steel pipe processing plants, NO.2B cold-rolled, heat-treated, pickled, and then finish-rolled to make the surface moderately bright. Due to the smooth surface, it is easy to regrind, making the surface brighter and widely used, such as tableware, building materials, etc. With surface treatments that improve mechanical properties, it is suitable for almost all applications.

Dull surface: NO.2D cold-rolled, heat-treated and pickled, its material is soft and its surface is silvery-white luster, which is used for deep-drawing processing, such as automotive components, water pipes, etc. Coarse sand NO.3 is a product ground with a 100-120 grinding belt. Has better gloss, with discontinuous coarse lines. It is used for building interior and exterior decoration materials, electrical products and kitchen equipment, etc. Fine sand is also a surface finish 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. The bright surface is a kind of special brightness, which can be directly used to make mirrors or other decorative products, etc. It is beautiful and can maintain brightness for a long time without worrying about corrosion. Specifically, what kind of surface processing grade should be selected, but also need to choose and use according to the characteristics of the product, try to be beautiful and practical.
