What are the functions of each surface treatment method of 420 stainless steel ball?

The surface treatment methods of 420 stainless steel ball mainly include polishing and fine grinding. Each treatment method has its specific function, which is described as follows:
Polishing: Polishing is to remove the roughness and oxide layer of the surface of 420 stainless steel ball by mechanical polishing, so that the surface becomes smooth and bright. Polishing can not only improve the beauty of stainless steel ball, but also improve the surface finish, making stainless steel ball more visually attractive. Polishing can be divided into physical polishing and chemical polishing according to the technique, and local polishing can be performed on a small part of the stainless steel ball. The surface quality of polished stainless steel ball is higher, which can meet the application occasions with high requirements for surface quality.
Fine grinding: Fine grinding is to grind off part of the metal fiber layer on the surface of 420 stainless steel ball by mechanical force to form a specific surface morphology. This treatment method can change the roughness and glossiness of the surface of stainless steel ball, and increase its decorativeness and practicality. The surface of stainless steel ball after fine grinding is flat, has certain corrosion resistance, is non-toxic and tasteless, and will not harm human health. Stainless steel frosting (a form of fine grinding) can create an effect similar to frosted glass, with advantages such as anti-corrosion and anti-pollution. This treatment method is widely used in the surface treatment of stainless steel metal products, including 420 stainless steel balls. Stainless steel balls after fine grinding can maintain their beauty for a long time and have excellent wear resistance and corrosion resistance.
In summary, polishing and fine grinding are two common surface treatment methods for 420 stainless steel balls. Polishing mainly improves the beauty and surface finish of stainless steel balls, and is suitable for applications with high surface quality requirements; while fine grinding increases its decorativeness and practicality by changing the roughness and glossiness of the stainless steel ball surface, and has advantages such as anti-corrosion and anti-pollution, and is widely used in the surface treatment of stainless steel metal products.
