Stainless steel processing refers to the process of cutting, folding, bending, welding and other stainless steel with stainless steel properties to finally obtain the stainless steel products required for industrial production. In the process of stainless steel processing, a large number of machine tools, instruments and stainless steel processing are needed. equipment. The classification of stainless steel processing equipment is divided into shearing equipment and surface treatment equipment, and the shearing equipment is further divided into open flat equipment and slitting equipment. In addition, from the thickness of stainless steel, there are points for cold and hot rolling processing equipment. Thermal cutting equipment mainly includes plasma cutting, laser cutting, water cutting and the like.
Stainless steel surface processing grade
Original surface: NO.1 Surface after heat rolling and heat treatment and pickling treatment. Generally used for cold-rolled materials, industrial tanks, chemical industrial equipment, etc., thicker from 2.0MM-8.0MM.
Blunt surface: NO.2D After cold rolling, after heat treatment and pickling, the material is soft and the surface is silvery white, which is used for deep drawing processing, such as automobile parts and water pipes.
Matte: NO.2B After cold rolling, heat treatment, pickling, and finishing rolling to make the surface a moderate bright. Because the surface is smooth, it is easy to re-grind, making the surface brighter and widely used, such as tableware and building materials. After surface treatment with improved mechanical properties, almost all uses are met.
Coarse sand NO.3 A product ground with a 100-120 grinding belt. It has better gloss and has discontinuous rough lines. Used in interior and exterior decorative materials, electrical products and kitchen equipment.
Fine sand: NO.4 A product ground with a grinding belt of size 150-180. It has better gloss, has discontinuous rough lines, and has finer stripes than NO.3. Used in baths, interior and exterior decoration materials, electrical products, kitchen equipment and food equipment.
#320 Products ground with a No. 320 grinding belt. It has better gloss, has discontinuous rough lines, and is thinner than NO.4. Used in baths, interior and exterior decoration materials, electrical products, kitchen equipment and food equipment.
HAIRLINE: HLNO.4 The continuous grinding of the appropriate size of the abrasive belt produces a grind pattern (subdivided from 150-320). Mainly used for architectural decoration, elevators, building doors, panels, etc.
Glossy: A product obtained by applying a bright annealing to BA after cold rolling and smoothing. The surface gloss is excellent and has a high reflectivity. Like a mirrored surface. Used in home appliances, mirrors, kitchen equipment, decorative materials, etc.
Application field
In the field of architectural applications, the surface finish of stainless steel is important for a number of reasons. A corrosive environment requires a smooth surface because the surface is smooth and not easily fouled. The deposition of dirt can rust or even cause corrosion of the stainless steel.
In the spacious hall, stainless steel is the most commonly used material for elevator decorative panels. Although the surface fingerprint can be wiped off, but it affects the appearance, it is best to use a suitable surface to prevent fingerprints.
Hygienic conditions are important in many industries, such as food processing, catering, brewing, and chemicals. In these applications, the surface must be easily cleaned daily, and chemical cleaners are often used.
Stainless steel is the best material in this area. In public places, the surface of stainless steel is often ridiculed, but one of its important characteristics is that it can be washed away, which is a remarkable feature of stainless steel over aluminum. The surface of aluminum tends to leave traces and is often difficult to remove. When cleaning the stainless steel surface, it should be cleaned along the lines of stainless steel, because some surface processing lines are unidirectional.
Stainless steel is best suited for hospitals or other areas where hygiene is critical, such as food processing, catering, brewing and chemicals, not only because it is easy to clean every day, but sometimes with chemical cleaners, and because it is not easy to breed bacteria. . Tests have shown that stainless steel has the same properties as glass and ceramics in this respect.
