AbstractThe alloy reinforced cast steel ball or sand has the material components of: C 0.60-0.85 wt%, Si 0.40-1.50 wt%, Mn 0.50-1.20 wt%, Cr 0.15-0.40 wt%, V 0.10-0.20 wt%, Mo 0.10-0.20 wt%, S 0-0.05 wt% and P 0-0.05 wt% other than Fe. With low carbon content and micro alloy elements Cr, V and Mo, the alloy reinforced cast steel ball or sand has reinforced strength, improved toughness, high impact strength and wear resistance and thus long service life. It is especially suitable for the surface shot blasting treatment and surface reinforcing treatment of high strength steel.
