Description
Chromium (CR) has a tendency to increase hardness, toughness and wear resistance of steel. Chrome steel is a chrome alloy carbon steel, not a chrome plated steel.
It has good superior performance, and has excellent wear resistance, deformation resistance, high load capacity and high contact fatigue performance after quenching and tempering.
Oil-hardened steel balls are commonly used in bearing manufacturing. Has high hardness, excellent deformation and wear resistance. Vacuum degassing and uniform hardening through electric furnace.
The extremely precise and smooth surface of our chrome steel balls ensures that you will not find any defects such as flat surfaces, pits, soft spots, and cuts.
We mainly produce chrome steel, the size is 7.9375mm ~ 150.mm. The main material is high chromium GCR15 or GCR15SiMn. Our balls are mainly used in the wind energy industry.
Chrome steel and other metal balls are manufactured using the following processes
