With the rapid development of economy, the steel ball is widely used in bearings, electronics, machinery, electric power, mining, metallurgy and other fields. According to its application, material and forging process, steel ball and is divided into several categories, each kind of steel ball has its unique properties and function.

(1) from the perspective of the application of classification. Steel ball can be divided into two categories, wear-resistant steel and bearing steel ball. Wear-resistant steel ball is mainly used in crushing industry, widely used in industrial applications; While bearing steel ball plays a significant role in the bearing industry.

(2) according to the mode of production. Steel ball can be divided into semi-solid forming, forging, casting and rolling four categories. The casting steel ball with its easy to realize the expansion of large-scale production in low investment advantage, become the main force in the steel ball production mode.

(3) according to the processing material classification. Steel ball can be divided into bearing steel ball, stainless steel ball, punch ball, alloy ball, steel ball, etc. In some special conditions, often need special material steel ball, to complete the required to achieve the function of the different environment. Alloy balls to carbon, chromium, manganese, molybdenum, etc as the main metal elements added, and through the way of forging, casting and rolling, spinning generated a globular shape alloy wear-resistant body, it is the crushing industrial ball in mines, the most important part of cement ball etc.

(4) according to the elements and its alloy ball forging process classification. Can be divided into the high manganese steel ball; Determination of manganese in nodular cast iron ball; Special alloy cast iron ball; Wet wear resistance cast ball; Low alloy wear-resistant cast ball; High alloy wear-resistant cast ball and so on all kinds of types. Because of their different features in the production of each take an important role in the life.
