      Surface processing method and application of stainless steel
      News Source: | Release Time:2019-12-27

      Stainless steel surface processing is through different processing methods, so that the surface of stainless steel has different luster, color, pattern, etc., in order to improve the appearance of stainless steel and achieve aesthetic effect.

      In addition, surface processing also has important functional effects, such as smooth stainless steel surface not only looks clean, but also easy to clean and keep clean; in corrosive environment, the smoother the surface, the better corrosion resistance; through cold pressing pattern to increase the strength, in the process of stainless steel products processing (such as deep drawing), it is hoped that the metal surface texture is slightly rough to hang the grease, Proper amount of grease can reduce tool wear and reduce tool indentation; wire surface processing and coating is to facilitate deep processing.

      Types of stainless steel surface processing

      The surface processing of stainless steel is usually divided into two categories: one is the surface obtained by the stainless steel production plant with different production processes, which is usually called rolling surface processing; the other is the surface processing of materials to change the surface level or property, which is called stainless steel surface deep processing.

      Rolling surface processing

      The stainless steel plate and strip produced by rolling mill usually go through hot rolling, cold rolling, annealing, pickling and finishing. Because the surface of cold-rolled stainless steel strip plays a special role in use, the surface processing of cold-rolled stainless steel sheet and strip can be divided into different types (or grades) according to different process methods. Stainless steel sheet and strip, especially cold-rolled steel sheet and strip, have a variety of surface processing types, which are regulated by national standards, such as common 2B, No.1, Ba surface.

      Deep processing of stainless steel surface

      For some special purposes, it is necessary to change the surface properties of stainless steel, which requires deep processing by different processes.

      1. Electroplated and evaporated surfaces

      In order to improve the surface properties of stainless steel, a layer of wear-resistant, scratch resistant and corrosion-resistant coating was coated on the surface of stainless steel by electroplating. In order to make the covering layer firmly combine with the metal substrate, the surface can be pretreated by different methods to remove the oil and rust on the surface. The advantage of electroplating is that it has almost no effect on the microstructure of the matrix material. It is mainly used for art and decoration.

      2. Electropolished surface

      In contrast to electroplating, electropolishing does not deposit chromium or nickel on the substrate. Instead, it uses stainless steel as anode and electrolyzes with specially formulated electrolyte to etch 2-40pm thick thin layer on the surface of stainless steel to obtain smooth, clean and bright body with excellent corrosion resistance.

      3. Mechanical polishing

      Mechanical polishing refers to using abrasive belt, polishing wheel, grinding wheel or other tools to grind the surface of stainless steel plate to obtain the corresponding surface effect. The effect of mechanical polishing usually includes snowflake sand, filament, lotus pattern, random pattern, fog surface and mirror surface. As a professional supplier of stainless steel polishing plate in Wuxi, Lishun stainless steel company provides various kinds of surface polished steel plate.

      4. Colored surface

      Coloring is immersion of stainless steel in hot chromic acid or sulfuric acid solution, and then cathodic hardening in another acid solution. The reaction of the metal with hot acid results in the formation of a basic colorless transparent film, but it shows color under the interference of light. After polishing and coloring, the metal luster is very high. These colored stainless steels not only have enhanced corrosion resistance, but also can be bent or stretched slightly.

      5. Surface painting

      Reprocessing (precoating) after coating is mainly used for roof building materials. After processing, it is mainly used for building materials. The surface of stainless steel is coated with fluorocarbon resin and silicone polyester, which increases the corrosion resistance in marine environment and makes the roof durable, pollution resistant and glare resistant.
