①The 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 greater than that of cast iron, and the density of alloy steel varies according to the density and content of the main alloying elements.

②The influence of the steel ball manufacturing method: the rolled and forged steel balls have Floating Hollow Ball 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 in it, so the density is low some.

③The 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.

④The 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.
