(%) = 0.14 to 0.38, and the balance of Ti and Inevitable (in terms of% by mass) of Fe and Fe in an amount of 0.8 to 1.5%, 4.8 to 5.5% and 0.030% A high-strength titanium alloy hot-rolled steel sheet in which cracks in the plate width direction are unlikely to advance during rewinding of a coil made of an impurity. (a) ND (normal to the hot-rolled sheet) direction, RD (hot rolling) direction, TD (hot rolling width) direction, c-axis (normal direction of the plane (0001) on the α) orientation θ the angle formed with the ND direction , the plane including the c-axis orientation and the ND direction of the surface and the angle formed by including the ND direction and TD direction Φ and, (b1), and θ is 0 degrees, 30 degrees or less, and, Φ, the entire circumference ( (B2) ? Is not less than 80 degrees but less than 100 degrees, and ? Is not more than ( ? ) The maximum strength (X2) of the X- (C) XTD / XND of not less than 4.0, among the (0002) reflection relative intensities of the X-rays by the crystal grains at 10 degrees. Q (%) = [O] + 2.77 [N]
