The invention provides hollow axle steel for a high-speed train. The hollow axle steel for the high-speed train comprises the following components with contents by mass: 0.19%-0.24% of C, 0.6%-1.1% ofCr, 1.3%-1.8% of Ni, 1.8%-2.4% of Mn, 1.8%-2.2% of Si, 0.22%-0.30% of Mo, 0.12%-0.20% of V, not greater than 0.010% of P, not greater than 0.003% of S, less than 10ppm of O, less than 0.5ppm of H, less than 30ppm of N and the balance Fe, wherein (Mn+Si) is not less than 3.6% and not greater than 4.2%. According to the hollow axle steel for the high-speed train, the mechanical property is improvedthrough alloying for the elements of Mn, Si, Cr, Ni, Mo, V and the like; and on the premise of meeting the ductility and toughness requirements of the working condition, the strength of the hollow axle steel for the high-speed train is remarkably increased, and the fatigue resistance of the hollow axle steel for the high-speed train is remarkably improved, so that increasing for the dimensions ofthe central hole of an axle is promoted, and the light weight of the axle for the high-speed train is realized.
