摘要

(1): 0.34 to 0.55; and the balance of Ti and impurities, wherein the alloy contains 0.001 to 1.5% of Fe and 0.02% or less of N, Wherein the tensile strength in the longitudinal direction of the pipe exceeds 900 MPa and the Young's modulus in the longitudinal direction of the pipe exceeds 130 GPa.Q = [O] + 2.77 x [N] + 0.1 x [Fe] (One)Here, [Fe], [O], and [N] are the content [mass%] of each element.;
