Chrome steel ball have the characteristics of high hardness, deformation resistance and corrosion resistance.It is mainly used for manufacturing bearing rings and rolling elements, such as making steel for internal combustion engines, electric locomotives, automobiles, tractors, machine tools, rolling mills, drilling machines, mining machinery, general machinery, and high-speed rotating high-load mechanical transmission bearings Balls, Rollers and Ferrules. In addition to manufacturing balls bearing rings, etc. It is sometimes used for manufacturing tools, such as dies and measuring tools.
Due to its specific characteristics such as great hardness, high wear resistance, good surface finish and low dimensional tolerances, the low-alloy martensitic AISI 52100 chromium steel is used for the manufacturing of bearings and valves.
Areas of application: Rolling bearing balls, Valves, quick connectors, precision ball bearings, vehicle components (brakes, steering, transmission), bicycles, aerosol cans, drawer guides, machine tools, lock mechanisms, conveyor belts, slide shoes, pens, pumps, rotating wheels, measuring instruments, ball screws, household electrical appliances.

1)Raw material.
In its initial stage, the ball appears in the form of a rod or wire. Secondly, quality control makes sure that the material composition is within a good range through metallurgical testing.
2) Header.
After passing the inspection phase, the raw material is then fed through a high speed header. This forms very rough balls.
3)Flashing.
The flashing process cleans up the headed balls so that they are somewhat smoother in appearance.
4)Heat Treatment.
An extremely high temperature process where the flashed balls are placed in an industrial oven. This hardens the ball.
5)Grinding.
In this phase, we grind the sphere of the ball to an approximate diameter of the final sphere size.
6)Lapping.
The lapping of the ball brings it to it's desired final dimension. This is the final forming process to keep the ball within grade tolerance limit.
7)Final Inspection.
Lastly, the quality control department accurately measures and tests the ball to ensure the highest quality.
