S-2 Tool Steel balls as a kind of hardened and high toughness ball, they provide good service in withstanding the abrasion of pulverized rock and mud slurries. As the most frequent application of S-2 rock bit balls is applied in drilling when making this kind of balls, they should achieve very good ruggedness and a smooth ground and polished finish are also required. These balls offer the tenacity and strength necessary for severe shock loads.
