Surface Treatment of Stainless Steel Sheet

Stainless steel surface treatment technology development

With the continuous development of science and technology of the economy, China's stainless steel industry has also made an attractive development, and at the same time, the stainless steel surface treatment and technology also get very rapid progress. The application of stainless steel development in a great level determines the level of development of surface disposal technologies. Here I talk about the technical condition of stainless steel surface disposal for your discussion. The stainless application development prospects will be more and more widely. With the expansion of the stainless steel use, door uses fingerprint contamination and food, medicine and other corrosion problems cannot be ignored, and this required the implementation of a resin coating. Pigmented coatings would lose the unique metallic luster and ornamental stainless steel. Therefore, in recent years, at the same time to prevent fingerprint contamination and corrosion, stainless steel manufacturers also develop the decorative stainless steel sheet, and it is widely used in the refrigerator, the dishwasher dryer, IH rice cooker and cooker door for decoration.

Corrosion Phenomena of Stainless Steel Sheet

At present, many stainless steel manufacturers will do the surface treatment on the stainless steel surface, i.e. the nature of varieties surface whitening process, making it generally more difficult to chemically react with the media and is etched. Surface mirror polished processing, surface coloring disposal. textured stainless steel sheet, due to its special microstructure and surface passivation film, is not corroded under any conditions, and it is corroded in some circumstance. Presence of corrosive media and incentives (such as scratches, splash, cutting slag), stainless steel can occur with the corrosive medium slow chemical and electrochemical reactions corrosion and corrosion under certain conditions, a fairly rapid pace corrosion phenomenon occurs especially to pitting and crevice corrosion. The corrosion mechanism of stainless steel is mainly electrochemical corrosion.

Various Stainless Steel Surface Processing Challenges

In the stainless steel processing, coil, bar-side welding or Attn party isothermal surface fire processing, color oxide occurs. Past, stainless steel exterior materials as motor gives people no rust, clean, sanitary, "Advanced" such a good impression, but on the other hand, is also associated with "cold dark negative impression, which is difficult for the family uses to universal is an important reason. This, transparent coating stainless steel sheet design has the coating layer on the surface, and has a very colorful ornamental performance, improve the design and texture of door products. At the same time, especially in recent years, the presentation of colored transparent coating, give people a sense of high soft ornamental, and also make it be able to rapidly growing popularity.
