Galvanizing of stainless steel

Zinc plating on stainless steel is a process of plating a layer of zinc on the surface of stainless steel. Stainless steel itself has the advantages of corrosion resistance, high temperature resistance and beauty, but it will still be corroded by some chemicals in some special environments, so it needs zinc plating to enhance its corrosion resistance. The following will introduce the characteristics, application and manufacturing process of stainless steel zinc plating.

trait

1. Strong corrosion resistance: Stainless steel itself has high corrosion resistance, and galvanized treatment can further enhance its corrosion resistance, so that it can be used in more harsh environments.

2. Good wear resistance: galvanized treatment can make the surface of stainless steel smoother, thus enhancing its wear resistance.

3. High aesthetics: Galvanizing treatment can make the surface of stainless steel appear metallic luster and more beautiful.

App application

1. Building field: Stainless steel zinc plating can be used for external walls, roofs, windows and other parts of buildings to enhance their corrosion resistance and aesthetics.

2. Food processing field: stainless steel zinc plating can be used to make food processing equipment, which can increase the corrosion resistance and hygiene of the equipment.

3. Medical device field: Stainless steel zinc plating can be used to manufacture medical devices, which can increase the corrosion resistance and hygiene of the devices.

manufacturing process

1. Pretreatment: clean the stainless steel surface to remove impurities such as oil stain and oxide.

2. Pickling: Soak the surface of stainless steel in acidic solution to remove the oxide and rust layer on the surface.

3. Galvanizing: Soak the surface of stainless steel after pickling in a solution containing zinc ions, and galvanize the surface of stainless steel through electrochemical reaction.

4. Post-treatment: After the galvanized stainless steel surface is cleaned and dried, the surface will be smoother and more beautiful.
