Product Description
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.
Applications: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.

Packing1.Firstly we pack the balls in cartons.
One type inside has two cartons.
For each carton, length: 22cm width:17cm height:10cm
Another type inside has four cartons:
For each carton, length: 15cm width:12cm height:10cm
2.Then, we pack our balls using wooden pallet in our export business :
1).Put the plastic paper in the pallet(waterproof).
The size of wooden pallet: 860mmm 800mm 750mm
2).Put the ball carton into the pallet ,and fix the pallet.
3).Hooping the pallet tightly using the steel rods
About the outside carton:
For each carton, length: 37cm width:25cm height:11cm
Generally, if you don't want packing with our company's logo and name, we offer neutral packing.
Quality Control
Before packing, surface inspection will be made.
First, all the finished products will be visually inspected two times.
After that, sample inspection is done each batch by visual inspection.
Last, sample inspection again is made by automatic checking and sorting machine.
