Stainless Processing Technology
Stainless processing refers to the process of cutting, bending, bending, welding, and other mechanical processing of stainless steel with the properties of stainless steel to finally obtain the stainless steel products required for industrial production. In the process of stainless processing, a large number of machine tools, instruments, and stainless steel processing are needed. equipment. Stainless processing equipment is classified into shearing equipment and surface treatment equipment and the shearing equipment is divided into Kaiping equipment and slitting equipment. In addition, from the thickness of stainless steel, there is 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 The surface is 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 to 8.0MM.
Blunt surface: NO.2D cold-rolled after heat treatment and pickling, its material is soft, the surface is silver-white, and it is 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.
Coarse sand NO.3 is a product grinded with a No. 100-120 grinding belt. Has better gloss, with discontinuous rough lines. Used in building interior and exterior decoration materials, electrical products and kitchen equipment, etc.
Fine sand: NO.4 is a product grinded with a 150-180 grit 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 a No. 320 abrasive 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.
Hairline: HL NO.4 is a product that produces a grinding pattern after continuous grinding with a polishing belt of appropriate granularity (subdivision No. 150-320). Mainly used for building decoration, elevators, building doors, panels, etc.
Bright surface: BA is a product obtained by cold rolling, bright annealing, 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.
Application Area
There are many reasons why the surface processing of stainless steel is important in the field of construction applications. The corrosive environment requires a smooth surface because the surface is smooth and not easy to accumulate. The deposit of dirt will cause stainless steel to rust and even cause corrosion.
In a spacious hall, stainless steel is the most commonly used material for elevator decorative plates. Although the fingerprints on the surface can be wiped off, it affects the appearance, so it is best to choose a suitable surface to prevent fingerprints from being left.
Sanitary conditions are very important to many industries, such as food processing, catering, brewing, and chemical industries. In these applications, the surface must be easy to clean every day, and chemical cleaning agents are often used.
Stainless steel is the best material in this regard. In public places, the surface of stainless steel is often scribbled. However, one of its important features is that it can be washed away. This is a significant feature of stainless steel over aluminum. It is easy to leave traces on the surface of aluminum, which is often difficult to remove. When cleaning the surface of stainless steel, you should clean up along the lines of stainless steel, because some of the lines processed on the surface are unidirectional.
Stainless steel is most suitable for hospitals or other areas where sanitary conditions are critical, such as food processing, catering, brewing, and chemical engineering. This is not only because it is easy to clean every day, and sometimes chemical cleaning agents are used, but also because it is not easy to breed bacteria. Tests have shown that the performance of stainless steel in this respect is the same as that of glass and ceramics.
