304 stainless steel process

The process of the color spray art processing method of stainless steel products is: stainless steel products → silk screen → etching → alkali treatment → silk screen → oxidation coloring → alkali treatment → finished product.

The process of the etching art processing method of stainless steel products is: stainless steel products → silk screen → etching → alkali treatment → oxidation coloring → finished product.

The chemical coloring method of stainless steel does not use pigments and dyes. Instead, the stainless steel is soaked in a heated concentrated chromium sulfate solution for chemical coloring. It is characterized by good food resistance. The ink used in this processing method must have very strong acid resistance, and generally use UV vulcanized ink with special properties that is compatible with the treatment process.
