3/8" Refined Tungsten Steel Ball Hard Alloy Ball for Valves,Cemented Tungsten Carbide Balls
The characteristics of tungsten carbide ball:
Tungsten Carbide balls are used in a variety of applications where extreme hardness and wear resistance is required.Tungsten Carbide has has emerged as a superior alternative to steel in many applications where severe conditions occur, such as high abrasion, corrosion and high temperatures.
The working process of tungsten carbide ball:
Heat treating: This high temperature process hardens the ball.
Grinding or polishing: The ball is then ground to the approximate diameter of the finished tungsten carbide balls. This polishing process the ball to the exact size required.
