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.

High requirements for smelting quality of bearing steel, and the content and distribution of sulfur, phosphorus and non-metallic inclusions need to be strictly controlled, because the content and distribution of non-metallic inclusions have a great impact on the life of bearing steel. The basic quality requirements for bearing steel are purity and uniform organization. Purity means that there are fewer impurity elements and non-metallic impurities, and the uniform structure means that the carbides in the steel should be fine and evenly distributed. The higher the amount of inclusions, the shorter of the life span. In order to improve the quality of smelting, electric furnace smelting and electroslag remelting have been used recently, and new processes such as vacuum smelting and vacuum consumable refining can also be used to improve the quality of bearing steel.

Most bearing rings and rolling elements are made of special steel. High-carbon chromium bearing steel (GCr15 and GCr15SiMn and ZGCr15 and ZGCr15SiMn) are used to manufacture ferrules and rolling elements with high hardness.

High-carbon chromium bearing steel is a large type of bearing steel, and is the most commonly used steel for manufacturing bearings and bearing parts. The most commonly used high carbon chromium bearing steels are GCr15 and GCr15SiMn, the former of which is the most used in my country's bearing industry.

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. 

We mainly produce chromium steel with a size of 7.9375mm to 82.55mm. The main material is high chromium GCR15 or GCR15SiMn.Our balls are mainly for wind energy industry.

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.

Influencing Factor

① The influence of material density: steel balls, cast iron balls, alloy steel balls, etc. Different materials have different densities. The density of steel is higher than that of cast iron. The density of alloy steel is based on the density and content of the main alloying elements.

② The influence of steel ball manufacturing method: Rolled and forged steel balls have a dense structure, so the density is very high. The structure of cast steel balls, cast iron balls or cast alloy balls is not very dense, and even has pores, so the density​​​ is lower.

③ The influence of the metallographic structure of the steel ball: the density under different crystal structures such as martensite, austenite, bainite, and ferrite is also different, which also affects the fineness of the crystal.

④ The influence of chemical composition elements: the different chemical compositions contained in the finished steel ball, such as iron, carbon, chromium, manganese, sulfur, phosphorus, etc., will affect the hardness and impact wear of the steel ball to different degrees. Generally speaking, if the chromium content is large, the steel ball has higher wear resistance.

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.
