Forged steel ball advantagei
The forged steel grinding ball is excellent in surface quality, toughness, and resistance to impact and abrasion. It won't break and lose circularity easily. The forging and stamping method that we use is that heating the metal until the temperature reaches 1050A C (A 50 A C), and utilizing the metalforming machinery to exert pressure onto the metal blank, then the metal blank coming out with plastic deformation to become the forge piece with certain mechanical properties, shape and dimension.

The forging can eliminate the defects such as porous as-cast microstructure generated during the smelting process of the metal, and optimize the microstructure. Meanwhile, as a result of the preservation of the complete metal flow line, the forge piece has superior mechanical performance to the casting with the same material. The forged steel grinding ball must use the super wear resistant material to ensure the abrasion resistance, such as the high-carbon steel materials compliant with the national standard, or the high wear resistant alloy steel material researched and developed independently by some companies themselves.
