Stainless steel surface treatment processes include: embossing, brushing, mirror, frosting, sandblasting, vacuum plating, etching, anti-fingerprint, etc. The specific methods of stainless steel surface treatment are as follows:

1. SANDBLASTING (SHOT PEENING) TREATMENT

Sandblasting uses compressed air as a power source to form a high-speed jet beam to spray the material (copper ore sand, quartz sand, corundum, iron sand, sea sand) at high speed onto the surface of the workpiece to be treated, so that the appearance or shape of the workpiece surface changes. Sandblasting has strong applications in engineering and surface technology, such as: improving the viscosity of adhesive parts, decontamination, optimizing surface burrs after machining, and matte surface treatment. Sandblasting is more uniform and efficient than manual polishing. This method of stainless steel treatment creates the low-key and durable characteristics of the product.

2. CHEMICAL TREATMENT

Chemical treatment is a general term for methods that use chemical or electrochemical treatment to generate a layer of stable compounds on the surface of stainless steel. Electroplating, as we often say, is an electrochemical treatment. This method includes using acid solution, anodic dissolution (electrolysis) alone or in combination to remove rust, and using phosphate treatment, chromate treatment, blackening, anodizing, etc. to form a protective film on the metal surface. This method can achieve complex pattern effects and create retro or modern design needs.

3. MIRROR TREATMENT

Mirror treatment of stainless steel, in simple terms, is to polish the surface of stainless steel. The polishing techniques are divided into physical polishing and chemical polishing. It is also possible to perform local polishing on the surface of stainless steel. The polishing levels are divided into ordinary polishing, ordinary 6K, fine grinding 8K, and super fine grinding 10K effects. The mirror surface gives people a sense of high-end simplicity, fashion and future.

4. SURFACE COLORING

Stainless steel coloring not only gives stainless steel products a variety of colors and increases the variety of product colors, but also improves the wear resistance and corrosion resistance of the product. There are many methods for surface coloring, which can be systematically divided into: 1. Chemical oxidation coloring method; 2. Electrochemical oxidation coloring method; 3. Ion deposition oxide coloring method; 4. High temperature oxidation coloring method; 5. Gas phase decomposition coloring method.

5. WIRE DRAWING PROCESS

Wire drawing is a common technique for stainless steel products. It can be made into straight lines, random lines, threads, corrugations and spiral lines according to the needs of decoration. Wire drawing on the surface of stainless steel gives people a super good feel, delicate luster, wear-resistant surface and personalized texture effect.

6. SPRAYING

Stainless steel spraying is substantially different from the coloring mentioned above. Depending on the material, some spray paints may damage the surface oxide layer of stainless steel. However, spraying can use simple processes to achieve different colors of stainless steel products, and different spray paints can also be used to change the feel of stainless steel. For example, the stainless steel water cups we use daily will use the spraying process.
