The influencing factors in steel ball production

① Material density affects: steel balls, cast iron balls, alloy steel balls, etc. The density of different materials varies. Steel has a higher density than cast iron, while alloy steel varies depending on the density and content of the main alloying elements.
② The influence of steel ball manufacturing methods: The microstructure of rolled and forged steel balls is dense, resulting in high density. The microstructure of cast steel balls, cast iron balls, or cast alloy balls is not very dense, and even has pores, resulting in lower density.
③ Effect of metallographic structure of steel ball: the density of different crystal structures such as martensite, austenite, bainite and ferrite is different, which also affects the crystal fineness.
④ Chemical composition element influence: Due to the different chemical components such as iron, carbon, chromium, manganese, sulfur, phosphorus, etc. contained in the finished steel ball, it has varying degrees of influence on the hardness and impact wear of the steel ball. Generally speaking, if the chromium content is high, the wear resistance of the steel ball is high.
