Stainless steel is a common metal material that has excellent corrosion resistance and aesthetics, and it is widely used in various fields. The most basic characteristics of stainless steel are its rust resistance under atmospheric conditions and corrosion resistance in various liquid media. This characteristic is directly related to the chromium content in the steel. The presence of chromium causes an invisible film to be formed on the surface of the steel, which can prevent oxidation and make the material "passivated" or resistant to corrosion. Adding other elements such as nickel or molybdenum can improve corrosion resistance, strength and temperature resistance. In order to further enhance the function and appearance of stainless steel, it is often necessary to perform surface treatment. This blog will shed light on the common surface classifications of stainless steel over the past few years.

Shiny Surface

The shiny surface refers to the stainless steel surface after polishing or polishing treatment, with a high finish and reflection ability. Shiny surfaces are commonly found in household goods, kitchenware and decorative areas. It is characterized by smooth and bright surface, which can effectively enhance the look and feel of the product. Stainless steel products with shiny  surfaces need to be polished and polished several times in the production process to obtain the ideal surface finish.

Mirror Surface

The mirror surface is a special bright surface, which has a higher finish and can show the general effect of a mirror. Mirror stainless steel is often used in architectural decoration, electronic products and high-end household goods and other fields. Mirror surface stainless steel products need to go through multiple polishing and polishing processes to eliminate surface texture and defects, and obtain a highly reflective mirror effect.

Sandblasted Surface

The sandblasted surface is a stainless steel surface with a rough texture, which is characterized by a rough surface. It can effectively increase the friction and anti-slip property of the product. Sandblasted stainless steel is commonly used in kitchen equipment, electronic product housings and industrial equipment. Sandblasting can sharpen the stainless steel surface by spraying high-speed particles to form a uniform fine granular texture, thereby increasing the roughness and touch of the surface.

Brushed Surface

The brushed surface is a stainless steel surface with a line texture. It is characterized by clear lines, giving a simple and powerful visual effect. Brushed stainless steel is often used in architectural decoration, elevator door covers and furniture. Brush processing can form a certain direction of texture on the surface of stainless steel through mechanical or chemical methods, so that it has a look and texture.

Sprayed Surface

The sprayed surface is a method of coating on the surface of stainless steel, which is characterized by the rich variety of colors and patterns that can be given to stainless steel. Sprayed stainless steel is often used in decorative panels, household goods and billboards and other fields. The stainless steel surface can be coated with a variety of colors and patterns by spraying liquid paint or powder paint, so as to achieve personalized customization of products.

Pickling Surface

The pickling surface is a method to remove the oxidation layer and dirt on the surface of stainless steel by pickling treatment, which is characterized by high surface finish and certain corrosion resistance. Pickling stainless steel is often used in chemical equipment, food processing equipment and medical equipment. Pickling can be done by soaking stainless steel products in an acidic solution, so that their surfaces are thoroughly cleaned and restored.

Electroplated Surface

The electroplated surface is achieved by plating a layer of metal or alloy on the surface of stainless steel using electrochemical method. It has good corrosion resistance and decorative uses. Electroplated stainless steel is often used in automotive parts, hardware accessories and jewelry. Electroplating can be done by using stainless steel products as cathodes and depositing metal ions on their surface to form a uniform metal coating.

Ceramic-coated Surface

The ceramic-coated surface is a method of coating ceramic materials on the surface of stainless steel, which is characterized by good wear resistance and high temperature resistance. Ceramic coated stainless steel is often used in kitchen utensils, stoves and electronic equipment. Ceramic coating treatment can be done by spraying or coating the ceramic material on the stainless steel surface to form a hard and durable ceramic protective layer.

Summary

It is widely known that stainless steel products can achieve the ideal effect in appearance and performance needed from the users, thus to its strong market competitiveness and impressive user experience. The above is a common classification of stainless steel surfaces, and each surface treatment method has its own characteristics and application areas. Choosing the right stainless steel surface treatment method can improve the texture and functionality of the product to meet the needs of different fields. In practical applications, it is necessary to settle on the appropriate stainless steel surface classification according to the specific situation, and in combination with product design and market demand, before performing reasonable surface treatment and processing.
