Whether the precision stainless steel strip can be sold well, its appearance is also very important. It can also be said that the application and development of precision stainless steel strip depends to a large extent on its surface treatment technology. Precision stainless steel belts have excellent characteristics such as high wear resistance, excellent anti-corrosion performance and not easy to rust.
According to the complexity of precision stainless steel belt products and different user requirements, mechanical polishing, chemical polishing, electrochemical polishing and other methods can be used to achieve mirror gloss.
Surface whitening treatment: During the processing of precision stainless steel strip, black oxide skin is produced by rolling, tying, welding or artificial surface fire heating treatment. Generally, hydrofluoric acid and nitric acid are used for strong corrosion removal. However, this method is costly, pollutes the environment, is harmful to the human body, improves management, and is highly corrosive, and is gradually being phased out.
Surface coloring treatment: The coloring of precision stainless steel strips not only imparts various colors to stainless steel products, but also increases the variety of products, but also improves the wear resistance and corrosion resistance of products.
