S-2 TOOL STEEL BALLS (ROCKBIT)
S-2 Tool Steel Balls are hardened throughout and have unusually good wear characteristics. These balls are intended for applications that require extreme toughness and strength. They provide good service in withstanding the abrasion, high shock resistance, severe pressure impact, etc.
We manufacture a complete line of Rockbit balls in various diameters. Rockbit Balls are designed for extreme ruggedness. The balls are made from S-2 tool steel and specially heat treated to provide excellent hardness and wear resistance combined with toughness and impact resistance to survive extreme shock loads found in the drilling industry.
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.
