Introduction
High-carbon chromium bearing steel refers to high-carbon alloy steel with a chromium content of 1.40-1.65%. 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. have good hardenability, and extremely strict control of sulfur and phosphorus. It is a high-grade high-quality steel. Make cold work mold steel. Specific gravity: 7.81.
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 and compact loads.
The chromium ball is made of the highest quality chromium alloy steel and is quenched to achieve 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.Our products enjoy high evaluation and satisfaction among customers.
