A variety of stainless steel pipe surface processing methods 2018-07-30 Do you think that the surface processing of stainless steel pipes is only: wire drawing, polishing, and solution treatment? Of course not, the production process of stainless steel pipes is different for different purposes. Perhaps you have discovered that there are so many ways to process the surface of stainless steel pipes. Original surface of stainless steel pipe: NO.1 The 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-8.0MM. Blunt surface: NO.2D after heat treatment and pickling after cold rolling, the material is soft, and the surface is silver White gloss, used for deep drawing processing, such as automotive components, water pipes, etc. Matte surface: NO.2B after cold rolling, heat treatment, pickling, and then finishing 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. Fine sand: NO.4 is a product grinded with grit size 150-180 grinding belt. It has better gloss, discontinuous rough lines and finer stripes than NO.3. Used in baths, interior and exterior decoration materials of buildings, electrical products, kitchen equipment and food equipment, etc. #320 The product is polished with No. 320 grinding belt. It has better gloss, discontinuous rough lines, and finer stripes than NO.4. Used in baths, interior and exterior decoration materials of buildings, electrical products, kitchen equipment and food equipment, etc. The hairline surface HAIRLINE: HL NO.4 is produced by continuous grinding with a polishing belt of appropriate granularity to produce a grinding pattern (subdivided No. 150-320). Mainly used for building decoration, elevators, building doors, panels, etc. Bright surface: BA is a product obtained by bright annealing after cold rolling and smoothing. The surface gloss is excellent and has a high reflectivity. Like a mirror surface. Used in home appliances, mirrors, kitchen equipment, decoration materials, etc.
