The invention provides an X80 hot-rolled steel plate for a hot bending elbow parent pipe. The X80 hot-rolled steel plate comprises the following components of, in percentage by mass, 0.07-0.11% of C,0.10-0.45% of Si, 1.65-1.85% of Mn, 0.020-0.060% of Al, 0.025-0.075% of Nb, 0.010-0.025% of Ti, 0.03-0.06% of V, less than or equal to 0.45% of Cr, less than or equal to 0.35% of Cu, 0.15- 0.45% of Ni, 0.15% -0.40% of Mo, less than or equal to 0.015% of P, less than or equal to 0.005% of S, less than or equal to 0. 0060% of N, less than or equal to 0.0005% of B, and the balance Fe and inevitable impurity elements. The yield strength (Rt0.5)of the obtained X80 hot-rolled steel plate for the hot bending elbow parent pipe is larger than or equal to 580 MPa, the tensile strength (Rm) is larger than or equal to 650 MPa, the yield ratio (Rt0.5/Rm) is less than or equal to 0.90%, the elongation (A) is larger than or equal to 30%, the Sharpy impact energy at minus 30 DEG C is larger than or equalto 220 J, the Sharpy impact energy at minus 60 DEG C is greater than or equal to 200 J, and the hardness is less than or equal to 265 HV10.
