1. Material influence: stainless steel ball, cast iron ball, alloy steel ball, etc. The density of different materials of solid steel ball is different. The density of steel is larger than that of cast iron, and the alloy steel varies according to the density and content of main alloying elements.
2. The effect of stainless steel ball manufacturing method: The rolled and forged steel ball has dense structure, so the density is large, and the structure of cast cast steel ball, copper ball cast iron ball or cast alloy ball is not dense, and even there are pores. Therefore, the density is smaller.
3. The effect of metallurgical structure of stainless steel ball: The density of different crystal structures such as steel ball, austenite, bainite and ferrite of martensite medical equipment is also different, which also affects the crystal fineness.
