Influencing factors of Steel Balls

① Material density influence: steel balls, cast iron balls, alloy steel balls, etc. Different materials have different densities. The density of steel is higher than that of cast iron, while that of alloy steel varies according to the density and content of main alloy elements.Stainless steel ballStainless steel ball.

② Influence of steel ball manufacturing method: rolled and forged steel balls have dense structure, so the density is high. The cast steel balls, cast iron balls or cast alloy balls are not dense, and even have air holes in them, so the density is low.

③ Effect of metallographic structure of steel ball: the density of martensite, austenite, bainite, ferrite and other different crystal structures is also different, which also affects the crystal fineness.

④ Influence of chemical components and elements: The different chemical components in steel ball products, such as iron, carbon, chromium, manganese, sulfur, phosphorus, etc., have different effects on the hardness and impact wear of steel balls. Generally speaking, the higher the chromium content, the higher the wear resistance of steel balls.
