This article mainly gives a brief introduction of some factors that can make a difference on the quality of sttel balls.
1.Material density effect: steel, cast iron ball, alloy steel ball, etc., different material, different densiy. the density of steel ball is bigger than cast iron ball; the density of alloy steel ball ivaries in accordance with the main alloy elements and content of different density.
2.The Production Methods： the density of the rolling ball or forging ball is bigger, on the other hand, casting steel ball, casting iron ball or the casting alloy ball is smaller.
3.The influence of metallographic structure ofsteel balls: martensite and austenite, bainite, ferrite, under different crystal, the density is different,too.
4.The influence of the chemical elements: The hardness and the abrasive resistance is different according to the different chemical elements in the steelballs， such as the content of iron, carbon, chromium, manganese, sulfur, phosphorus and other elements.
