Product Information

304L stainless steel pipe with external polished surface is a special kind of stainless steel pipe. Its surface is treated by mechanical polishing process to improve the corrosion resistance of the outer pipe wall, remove surface oxide scale, remove scratches generated during processing, and improve the smoothness of the pipe wall. This treatment method is particularly suitable for application scenarios that have high requirements for surface precision, such as the production of electronic product casings and bathroom products. Specifically, the application fields of 304L stainless steel pipe with external polished surface include:

Electronic product casings: For electronic product casings, most of the requirements for the pipe wall of 304L stainless steel product pipes are 2B surface, that is, a matte effect without brightness. The pipe wall roughness is about Ra0.4μm. Pipes and fittings with such requirements basically have no obvious oxide scale, rust, scratches, etc. Therefore, the process requirements are not harsh and the cost is not high, making it the preferred stainless steel product for electronic and electrical products.

Bathroom mirror pipes: 304L stainless steel precision polished pipes dedicated to bathrooms are often used to make steel pipes with mirror effects, that is, the so-called 8K mirror pipes, with a roughness between Ra0.1 and 0.2μm. This kind of surface has very high glossiness and has a high-end and fashionable visual effect. Due to the higher requirements for surface precision, the process cost will also increase. 304L stainless steel has good corrosion resistance, excellent processing performance and good welding performance, and is widely used in occasions that require good welding performance, such as petrochemical industry, food industry, medical equipment and nuclear power plants. In addition, 304L stainless steel also has good intergranular corrosion resistance and is suitable for making equipment such as heaters, boilers and heat exchangers.
