Stainless steel processing technology refers to the process of mechanically processing stainless steel by shearing, folding, bending, welding, etc. based on its properties to ultimately obtain stainless steel products required for industrial production. During the stainless steel processing, a large number of machine tools, instruments and stainless steel processing equipment are needed. Stainless steel processing equipment is classified into shearing equipment and surface treatment equipment. Among the shearing equipment, it is further divided into uncoiling equipment and slitting equipment. In addition, based on the thickness of stainless steel, there are distinctions between cold and hot rolling processing equipment. Thermal cutting equipment mainly includes plasma cutting, laser cutting, water jet cutting, etc.
Original surface: The surface of NO.1 that has undergone heat treatment and pickling after hot rolling. It is generally used for cold-rolled materials, industrial tanks, chemical industry equipment, etc. The thickness is relatively thick, ranging from 2.0MM to 8.0MM.
Blunt surface: NO.2D cold-rolled products that have undergone heat treatment and pickling have a soft texture and a silver-white luster on the surface. They are used for deep drawing processing, such as automotive components and water pipes.
Matte: NO.2B is cold-rolled, then heat-treated, pickled, and finally processed by fine rolling to achieve a moderately bright surface. Due to its smooth surface, it is easy to regrind, making the surface even brighter. It has a wide range of applications, such as in tableware and building materials. After surface treatment that improves mechanical properties, it almost meets all applications.
Coarse sand: NO.3 is the product ground with 100-120 grit grinding belts. It has a good gloss and discontinuous coarse texture. It is used for interior and exterior building decoration materials, electrical products and kitchen equipment, etc.
Fine sand: NO.4 is the product ground with a grinding belt of particle size 150-180. It has a relatively good gloss, with discontinuous coarse stripes, and the stripes are finer than NO.3. It is used for bathhouses, interior and exterior decoration materials of buildings, electrical products, kitchen equipment and food equipment, etc. Product ground with 320 # grinding belt. It has a relatively good gloss, with discontinuous coarse stripes, and the stripes are finer than NO.4. It is used for bathhouses, interior and exterior decoration materials of buildings, electrical products, kitchen equipment and food equipment, etc.
HAIRLINE: HLNO.4 products with grinding patterns generated by continuous grinding with polishing abrasive belts of appropriate particle size (subdivided into 150-320 grades). It is mainly used for architectural decoration, elevators, doors and panels of buildings, etc.
Bright surface: The product obtained by cold rolling BA followed by bright annealing and then leveling. The surface gloss is excellent and it has a very high reflectivity. The surface is like a mirror. It is used for household appliances, mirrors, kitchen equipment, decorative materials, etc.
