AISI S-2 TOOL STEEL BALLS

S-2 Tool steel balls are design to achieve extreme ruggedness. The ball surface has smooth ground and polished finish. These balls provide the toughness and strength necessary for severe shock loads. S-2 Tool steel balls are hardened throughout and have unusually good wear characteristics. S-2 Tool Steel Balls find most frequent use in oil field equipment and offshore drilling operations. They provide good service in withstanding the abrasion of pulverized rock and mud slurries.
