High Performance Forging Steel Ball , Ball Mill Grinding Balls for mining
Forged steel Balls are made from high carbon steel bars with the proper alloying elements.
Bars are heated to forging temperatures and formed into nearly perfect spheres.
Then, balls are heat-treated to provide the necessary wear and impact resistance properties.
