Introduction to Stainless Steel Grinding Balls

Stainless steel grinding balls are commonly used in planetary ball mills, roller ball mills, stirred ball mills, vibration ball mills, and other types of ball mills for ultra-fine grinding and dispersion of materials.Stainless steel grinding balls are typically produced through a stainless steel forging process. Currently, the commonly used materials for stainless steel balls include 201, 302, 304, 316, 316L, 420, and 440C.

Definition of stainless steel: Steel containing more than 12.5% chromium, with high resistance to corrosion from chemical substances (acids, alkalis, salts).
Stainless steel does not mean it will never rust, but rather that it is resistant to rust. The principle lies in the addition of chromium, which forms a dense layer of chromium oxide on the surface of the steel. This layer effectively prevents further contact between the steel and air, blocking oxygen in the air from penetrating the steel, thereby achieving the effect of preventing rust.

Characteristics of Stainless Steel Grinding Balls

1 Generally non-magnetic, but may become magnetic after burnishing; can be demagnetized, HRC ≤ 26.
2. Has good rust and corrosion resistance.
3 Good sphericity, smooth surface.
4. Suitable for grinding a variety of materials, cost-effective.
