Chemical coloring method of stainless steel without the use of pigments and dyes. Instead, the stainless steel is immersed in a heated concentrated chromium sulfate solution for chemical coloring, which is characterized by good food resistance. The ink used in this processing method must have very strong acid resistance. Generally, UV vulcanized ink with special properties suitable for the disposal process is used.

It can be roughly divided into two types. There are many ways to process the surface of stainless steel. One is the artistic processing of treating stainless steel to make it look glossy, and the use of gloss contrast to form a pattern; the other is the artistic processing of giving color in the composition of the pattern. Among them, typical examples of the screen printing method are etching processing and color spray processing.

The surface color of stainless steel is screen-printed acid-resistant protective film, and etching processing method. Then it is etched with ferrous chloride solution to form an artistic pattern by spraying color particles after screen printing to form a pear skin-like surface and form an artistic pattern.

In order to adapt to the diversification of stainless steel uses and the increasingly high artistic requirements, in recent years. The “Black Art with Color” processing method was developed and became the mainstream in this field. The methods for imparting color to stainless steel include the method of firing black ink by screen printing and the chemical coloring method.
