1. Chemical composition

Based on material,the forged steel balls are defined into 7 brands. And The chemical composition is shown in the following:

Brand	Material	C	Mn	Si	Cr	S	P	V
Special-1	50MN	0.48-0.56	0.70-1.0	0.17-0.37	≤0.25	≤0.035	≤0.035
Special-2	60MN	0.57-0.65	0.70-1.0	0.17-0.37	≤0.25	≤0.035	≤0.035
Special-3	65MN	0.60-0.70	0.90-1.20	0.17-0.37	≤0.25	≤0.035	≤0.035
Special-4	75Mn	0.72-0.92	0.17-0.37	0.17-0.37	0.4-0.6	≤0.035	≤0.035
Special-5	75MnCr	0.70-0.85	0.7-0.8	0.17-0.37	0.2-0.7	≤0.03	≤0.03
Special-6	75SiMn	0.70-0.90	0.7-1.2	0.4-0.8	≤0.25	≤0.03	≤0.03
Special-7	Wear-resistant Alloy	0.5-0.65	0.4-1.0	1.4-1.8	0.9-1.2	≤0.03	≤0.03	0.1-0.2

3.Hardness of Grinding Steel Ball (HRC)

According to the theory and tests, the hardness of forged steel ball is shown in the following:

Brand	Material	Impact Test AK.J/cm2	Endurance Test Times(5m)	Dia 25mm-60mm		Dia 70mm-100mm
Brand	Material	Impact Test AK.J/cm2	Endurance Test Times(5m)	Surface	Core	Surface	Core
Special-1	50MN	≥12	≥10000	≥56	≥48	≥56	≥40
Special-2	60MN	≥13	≥10000	≥58	≥50	≥58	≥42
Special-3	65MN	≥15	≥12000	≥60	≥50	≥60	≥42
Special-5	75MnCr	≥17	≥12000	≥60	≥52	≥60	≥50
Special-6	75SiMn	≥16	≥12000	≥60	≥50	≥60	≥48
Special-7	Wear-resistant Alloy	≥17	≥12000	≥60	≥54	≥60	≥52
