Forged Steel Ball

 

Forged steel ball is a kind of wear-resistant grinding steel ball. It is processed from round steel bar. It has a relatively smooth surface, high hardness, low breakage rate during use, and is resistant to grinding. According to different materials, it is mainly divided into carbon steel, manganese steel and special steel. Our company can produce forged steel balls with a diameter of 20-350mm, which are widely used in various ball mills in mines, cement plants, power plants, building materials, etc.
