For mechanical processing or plate cutting, steel and steel will be dealt with. However, one problem is that steel is easily oxidized. How can stainless steel be maintained? What about stainless steel oxidation rust? Here are some experiences for your reference.

Scientifically speaking, stainless steel refers to steel that is resistant to weak corrosive media such as air, steam, and water, and chemically etched media such as acids, alkalis, and salts. It is also called stainless acid-resistant steel. In practical applications, steels that are resistant to weak corrosive media are often referred to as stainless steels, and steels that are resistant to chemical corrosion are known as acid-resistant steels. Because of the difference in chemical composition between the two, the former is not necessarily resistant to chemical media corrosion, while the latter is generally non-rust. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel.
According to the complexity of the stainless steel products and the user's requirements, different methods such as mechanical polishing, chemical polishing, and electrochemical polishing can be used to achieve gloss. Here are the advantages and disadvantages of these three methods. For your reference, use mechanical polishing: Good leveling, bright labor intensity, serious pollution, difficult to process complex parts, declining gloss, high investment and cost, simple, medium, and small Products, complex parts can not be processed. The gloss of the entire product is less than the same, and the gloss retention time is not long. Chemical polishing: Less investment, complex parts can be thrown, high efficiency, insufficient brightness of fast light, polishing liquid to be humidified, gas overflow, and wind-proof equipment. For complex products, products with low lightness requirements can be processed in small batches with more cost-effective electro-chemical polishing: mirror gloss, long-term maintenance, process stability, less pollution, low cost, and good anti-pollution properties. One-time large investment, complex parts to install tooling, auxiliary electrodes, mass production to reduce temperature pollution products, requires a long time to maintain the mirror light, bright products. The process is stable, easy to operate, can be widely used to promote the use of stainless steel coloring not only gives a variety of stainless steel products, increase the color of the product varieties, but also improve product wear resistance and wear resistance.
Stainless steel coloring methods are as follows:
(1) Ion-deposited oxides or oxides.
(2) High temperature oxidation method.
(3) Chemical oxidation method. Electrochemical oxidation.
(4) Gas-phase cracking method Brief description of various methods is as follows:
(1) The ion-deposited oxide or oxide method is to place a stainless steel workpiece on a vacuum coating machine for vacuum evaporation plating: for example, a titanium-gold watch case and a watch band. It is generally golden yellow. This method is suitable for processing large quantities of products. Because of the large investment and high cost, small-volume products are uneconomical.
(2) The high-temperature oxidation method is in a specific molten salt, immersed in the workpiece to maintain a certain range of processes, so that the workpiece to form a certain thickness of oxide film, and showing a variety of different colors.
(3) The chemical method is to form the color of the film by chemical oxidation in a certain solution. Generally, there are many “cause to use†methods, but to ensure that the color of a batch of products is consistent, control must be performed using a reference telegram.
(4) The electrochemical method, which is the color of a film formed by electrochemical oxidation in a specific solution, is used in this commercial application.
(5) Gas-phase cracking method, which is more complex and less applicable in industry.
