Introduction
Chrome steel 52100 is a versatile material for many applications. The chromium steel ball contains high chromium, and has excellent surface quality and high bearing capacity due to being quenched. Throughout the manufacturing process, statistical process control can ensure tolerance accuracy, good surface finish and consistent high quality.
On the basis of GCr15 steel, the content of Si and Mn is appropriately increased to improve its hardenability and elastic limit, and its wear resistance is also better than that of GCr15. The applicable size range for manufacturing rolling elements is larger than that of GCr15.
The bearing steel adopts low temperature tempering. Temperature: 150~250 degrees. Under the premise of maintaining high hardness and high wear resistance, the internal stress and brittleness can be reduced to avoid cracking or premature damage during use.
We mainly produce chromium steel with a size of 7.9375mm to 82.55mm. The main material is high chromium GCR15 or GCR15SiMn.
The ball has high precision, good surface smoothness, standard hardness and excellent wear resistance. Our products have been widely exported to Europe, America, Japan, Korea etc.
GCr15 notice:
1. The residual copper content (melting analysis) of the steel for bearing steel pipes should not exceed 0.2%.
2. The oxygen content is measured on the billet or steel.
3. The sulfur content (melting analysis) of wire rod steel should not exceed 0.02%.
Application
Our steel balls can be used in many industrial fields, such as wind power bearing, rolling media, ball bearings, vibration polishing, linear motion components.

Properties and Advantage
[High-quality material] Made of high-quality chromium steel, high-grade bearing steel, corrosion resistance, high precision and high hardness. Polished surface, smooth without burrs, standard shape and high precision, completely round.
[Anti-rust] Corrosion resistance and high oxidation resistance. It is also suitable for humid environments. The surface is coated with a small amount of grease to improve lubrication and prevent corrosion and rust.
[Long use] The heat treatment process can make the bearing ball stronger and bear high pressure and wear resistance.
[Wide application] Widely used in wind turbine bearings, yaw bearing, slewingring bearing and so on.
