The stainless steel material generates a colored oxide on the surface under the action of a laser heat source, or forms a colorless and transparent oxide film, which presents various colors due to the interference effect of light film. This is the basic principle of stainless steel color marking, simple It is said that under the action of the laser, the surface of the stainless steel has a laser thermal effect, and the laser energy is different, and the stainless steel surface also exhibits different colors.

Conventional stainless steel color preparation methods such as chemical coloring and electrical chemical coloring used in the past have high energy consumption, large pollution, and difficulty in achieving fine coloration. In contrast, stainless steel laser color marking has unique advantages.
