Stainless steel basic 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，which 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: HL/NO.4 is a product with a grinding pattern (subdivided No. 150-320) generated by continuous grinding of a polishing abrasive belt with 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.
