S-2 (Tool Steel) Rockbit Ball/Swivel Balls for /Tricone Rock Bits/Alloy Steel Ball

S-2 TOOL STEEL BALLS (ROCKBIT) Rock Bit S-2 Tool Steel balls are designed to work well in very extreme conditions that are common when drilling deep into the ground. The balls provide the strength and toughness that is required to withstand heavy force and the abrasion of pulverized rock. These balls also have unusually good wear characteristics due to the materials hardening capabilities.Rock Bit S-2 Tool Steel balls are manufactured for bearings that are used in well drilling, oil field drilling and equipment and offshore drilling platforms. APPLICATION 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. Material AISI Military   ASTM UNS  AMS DIN JIS/SUJ S-2 Tool Steel S-2          A-681 T-41902 Additional testing may be required to certify that materials comply with specific standards.
