The invention relates to a high tensile toughness hydraulic pillar seamless steel tube, which solves the problems that in the prior hydraulic prop seamless steel tube, either the cost is high, or thestrength and the toughness is low, and the economic and safe combination property is not provided. According to the weight percentage, the high tensile toughness hydraulic pillar seamless steel tube comprises 0.15 percent-0.35 percent of C, 0.10 percent to 0.60 percent of Si, 1.00 percent to 2.00 percent of Mn, 0.02 percent to 0.07 percent of Nb, 0.01 percent to 0.06 percent of Al, 0.02 percent to0.12 percent of Ti, lower than 0.025 percent of P, lower than 0.024 percent of S and lower than 0.0035 percent of O.
