Introduction of steel ball
 
GCr15 steel has low alloy content and good performance. It is currently the most widely used bearing steel. After quenching and low temperature tempering, it will have higher hardness and uniform good structural properties. This kind of steel has general cold working plasticity, poor welding performance, high sensitivity to the formation of white spots, and temper brittleness.
 
Metal balls are spherical rolling elements that can provide rotary or linear motion for ball valves, check valves, bearings and other mechanical equipment. They are usually made of alloy steel, carbon steel or stainless steel. Its main features are composed of the outer diameter, tolerance, surface roughness and tolerance of the steel ball. The outer diameter (OD) is the total width or average diameter of the ball.
 
The basic quality requirements of bearing steel are purity and uniform organization. Purity means less impurity elements and non-metallic impurities, and a uniform structure means that the carbides in the steel should be fine and evenly distributed. There are high requirements on the quality of smelting of bearing steel, and the content and distribution of sulfur, phosphorus and non-metallic inclusions must be strictly controlled, because the content and distribution of non-metallic inclusions have a great impact on the life of bearing steel. The higher the inclusion content, the shorter the life span. In order to improve the quality of melting, electric furnace melting and electroslag remelting have recently been used, and new processes such as vacuum melting and vacuum consumable refining can also be used to improve the quality of bearing steel.
 
High-carbon chromium bearing steel refers to high-carbon alloy steel with a chromium content of 1.30-1.65%. Its characteristics are: the microstructure after heat treatment is relatively uniform and stable, good wear resistance, high stress fatigue strength, good dimensional stability and wear resistance.
 
This type of steel can meet the processing requirements under general working conditions. The brand numbers of ordinary high-carbon chromium bearing steel are GCr15 and GCr15SiMn. The performance of these two types of bearings is basically the same. But the hardenability of GCr15SiMn is better than GCr15, so GCr15SiMn is used for relatively large bearing parts. Because GCr15SiMn has high crack sensitivity and low impact resistance, it cannot fully meet the requirements for thick-walled bearings and mine bearings. Therefore, the railway department does not allow the use of CGr15SiMn on passenger car bearings. It is also limited to thick-wall rolling mills and mining machinery under large compact loads.
 
The chromium ball is made of the highest quality chromium alloy steel and is quenched for maximum strength and service life. Ideal applications for chrome balls include rolling media, spray tank mixing, ball bearings, wind turbine bearings and linear motion components. The most widely used in various industries.
 
The surface of our chrome steel balls is extremely precise and smooth, ensuring that you will not find any defects such as flatness, dents, soft spots and cuts.
 
We mainly produce chrome steel with sizes ranging from 7.9375mm to 82.55mm. The main material is high chromium GCR15 or GCR15SiMn. Our balls are mainly used in the wind energy industry.
