The Processing Method of 304 Stainless Steel

Etching method

The etching process is to screen the acid-resistant protective film on the surface of the stainless steel, and then etch it with a ferrous chloride solution to form an artistic pattern.


Spray color method

The spray color method is to spray the color particles after screen printing to form a pear-like surface to form an artistic pattern.


Crafting process

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

The chemical coloring method of stainless steel, instead of using pigments and dyes, is to chemically color the stainless steel by immersing it in a heated concentrated chromium sulfate solution. This process is characterized by good food resistance. The ink used in this processing method has a very strong acid resistance, and generally uses a UV-curable ink having a special property compatible with the treatment process.


Stamping processing

Stainless steel products, especially stainless steel belts, often use the punching machine for stamping products. Stamping includes straight-through and stretch. Generally, the hardness is less than 1/2, and the tensile and bending are used. The hardness is higher than 1/2, which is hard.
