Product Details
Steel balls are divided into grinding steel balls, forged steel balls, and cast steel balls according to the production process. According to the processing materials, it is divided into bearing steel balls, stainless steel steel balls, carbon steel steel balls, copper bearing steel balls and alloy steel balls. Among them, the bearing steel ball is an important basic component of the industry. The alloy steel ball is a spherical shape made by forging, spinning, rolling, and casting with carbon, chromium, manganese, molybdenum and other metal elements as the main added metal elements. Ferroalloy special-shaped wear-resistant body, it is an important part of today's crushing industrial mine ball and cement ball.
Bearing steel balls have a long history of use in the precision bearing industry and life, and their applications are more extensive. It can be said that most of the places where there is rotation, there are steel balls, commonly known as steel balls and steel balls.
High-carbon chromium bearing steel refers to high-carbon alloy steel with a chromium content of 1.40-1.65%. It is characterized by relatively uniform and stable structure after heat treatment, good wear resistance, high stress fatigue strength, good dimensional stability, and good wear resistance.
This type of steel can meet the processing requirements under general working conditions. The grades of ordinary high-carbon chromium bearing steel are GCr15 and GCr15SiMn. The performance of these two bearings is basically the same. But the hardenability of GCr15SiMn is better than GCr15, so GCr15SiMn is used for larger bearing parts.
Because GCr15SiMn has high crack sensitivity and low impact resistance, it cannot fully meet the requirements of thick-walled bearings and mining bearings. Therefore, the railway department does not allow the use of CGr15SiMn on passenger car bearings. It is also limited to thick-walled rolling mills and mining machinery under large compact loads.
Our steel balls are used in various industries, such as oil fields, automobiles, agriculture and food applications, material handling, energy sectors and bearings.
The surface of our chrome steel balls is very precise and smooth, ensuring that you will not find any defects such as flatness, dents, soft spots and cuts.
