Stainless steel processing refers to the process of cutting, folding, bending, welding and other mechanical processing of stainless steel based on the properties of stainless steel to finally obtain stainless steel products required for industrial production. In the process of stainless steel processing, a large number of machine tools, instruments, stainless steel processing equipment. Stainless steel processing equipment is classified into shearing equipment and surface treatment equipment, and shearing equipment is further divided into flattening equipment and slitting equipment. In addition, according to the thickness of stainless steel, there are cold and hot rolling processing equipment. Thermal cutting equipment mainly includes plasma cutting, laser cutting, water cutting and so on.
Stainless steel surface finish grade 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. 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. Matte surface: 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. 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: NO.4 products ground with a grinding belt with a particle size of 150-180. Has better gloss, with discontinuous coarse lines, and the stripes are thinner than NO.3. It is used for baths, interior and exterior decoration materials of buildings, electrical products, kitchen equipment and food equipment, etc. #320 Product ground with No. 320 abrasive belt. It has better gloss, with discontinuous rough lines, and the stripes are thinner than NO.4. It is used for baths, interior and exterior decoration materials of buildings, electrical products, kitchen equipment and food equipment, etc. Hairline surface HAIRLINE: HLNO.4 is a product with a grinding pattern (subdivided 150-320) produced by continuous grinding with a polishing abrasive belt of appropriate particle size. Mainly used for architectural decoration, elevators, doors and panels of buildings, etc. Bright surface: BA is cold rolled, bright annealed, and flattened. Excellent surface gloss and high reflectivity. like a mirror surface. Used in home appliances, mirrors, kitchen equipment, decorative materials, etc. Application field: There are many reasons why surface finishing of stainless steel is important in architectural applications. Corrosive environments require smooth surfaces because smooth surfaces are less prone to fouling. Dirt deposits can rust or even cause corrosion in stainless steel. In spacious halls, stainless steel is the most commonly used material for elevator decorative panels. Although the fingerprints on the surface can be wiped off, it will affect the appearance. Therefore, it is best to choose a suitable surface to prevent fingerprints. Hygienic conditions are important in many industries, such as food processing, catering, brewing, and chemical industries, where surfaces must be easy to clean on a daily basis, often with chemical cleaning agents. Stainless steel is the best material for this. In public places, the surface of stainless steel is often scribbled. However, one of its important properties is that they can be washed away, which is a distinguishing feature of stainless steel over aluminum. The surface of aluminum tends to leave marks that are often difficult to remove. When cleaning the stainless steel surface, it should be cleaned along the lines of the stainless steel, because some surface processing lines are unidirectional. Stainless steel is best used in hospitals or other areas where hygiene is critical, such as: food processing, catering, brewing and chemical industry, not only because it is easy to clean every day, sometimes with chemical cleaning agents, but also because it is less prone to bacteria growth . Tests have shown that stainless steel performs as well as glass and ceramics in this regard.
