The invention discloses a high-carbon low-chromium abrasion-resistant steel ball. The steel ball comprises, by weight, 0.8%-1% of C, 0.2%-0.4% of Si, 0.7%-0.9% of Mn, 0.8%-1% of Cr, 0.06%-0.08% of Ni, 0.07%-0.08% of Mo, 0.3%-0.5% of W, 0.02%-0.04% of Al, 0.2%-0.4% of Cu, 0.0006%-0.001% of B, 0.03%-0.04% of Ti, 0.17%-0.19% of V, 0.01%-0.013% of P, 0.001%-0.0013% of S and the balance Fe. The high-carbon low-chromium abrasion-resistant steel ball is low in cost, little in pollution, high in abrasion resistance, good in toughness and high in impact resistance.
