Introduction
Steel balls are divided into grinding steel balls, forged steel balls, and cast steel balls according to the production process. According to the processing material, it is divided into bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls and alloy balls. Among them, the bearing steel ball is an important basic component of the industry, and the alloy steel ball is a spherical shape formed by forging, spinning, rolling and casting with carbon, chromium, manganese, molybdenum and other metal elements as the main added metal elements. Shaped ferroalloy wear-resistant body, it is the most 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 they are more widely used. It can be said that most of the places where there is rotation, there are steel balls, commonly known as steel balls and balls.
Influencing Factor
① The influence of material density: steel balls, cast iron balls, alloy steel balls, etc., the density of different materials is different, the density of steel is higher than that of cast iron, and the density of alloy steel varies according to the density and content of the main alloy elements.
② The influence of the steel ball manufacturing method: the rolled and forged steel balls have a dense structure, so the density is high, and the structure of the cast steel ball, cast iron ball or cast alloy ball is not very dense, and even has pores, so the density is low some.
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 crystal fineness.
④ The influence of chemical composition elements: the different chemical composition 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 varying degrees. Generally speaking, If the chromium content is large, the steel ball has high wear resistance
Throughout the manufacturing process, statistical process control assures tolerance accuracy, fine surface finish and a consistent high quality. are the most widely used in the ball and roller bearing industry and for a variety of automobile applications.
We mainly produce chromium steel with a size of 7.9375mm to 82.55mm. The main material is high chromium GCR15 or GCR15SiMn.
Most importantly, we can customize our products to suit various needs of our customers.
