Influence factors of steel ball Oct 26, 2017

① material density influence: steel ball, cast iron ball, alloy steel ball, different material density, steel density is larger than cast iron, alloy steel depends on the density and content of the main alloying elements are different.

② Steel Ball Manufacturing method influence: Rolling and forging of the steel ball its compact structure, so density, casting cast steel ball, cast iron ball or cast alloy ball, such as the organization is not very dense, even the gas hole, so the density is smaller.

The microstructure effect of ③ steel ball: martensite, Austenite, Bainite, ferrite and other crystal structures are different in density, and have effect on crystallization fineness.

④ Chemical composition element influence: Steel Ball finished products because of the chemical composition, such as iron, carbon, chromium, manganese, sulphur, phosphorus and other ingredients, the hardness of the steel ball, impact wear has a different degree of influence, generally speaking, high chromium content, the steel ball wear resistance.
