8k is actually a surface treatment standard for stainless steel. The surface of the stainless steel tube is polished and ground, and the surface is as bright as a mirror, which can reflect objects and people, which is called mirror surface 8K. Everyone knows that stainless steel pipe is a kind of chromium-nickel alloy steel, and “8” in 8k refers to the proportion of alloy components (304 stainless steel mainly refers to the content of nickel element), and “k” refers to the reflectivity level after polishing (K level is specular reflection level). Therefore, the 8K mirror surface is also the mirror surface level reflected by the chrome-nickel alloy steel.
In addition, according to the fineness of the stainless steel surface, 6k, 10k, and other stainless steel tubes are also extended. The larger the number, the higher the surface fineness. But it’s not that the higher the surface fineness, the better the stainless steel pipe, the main thing is suitability. However, the higher the value of k, the higher the process requirements and the higher the price for sure.

In addition to the above fields, it is also widely used in construction, automobile, electronics, furniture and other industries
