    摘要: High-strength steel having excellent hydrogen-induced crack resistance, particularly in an environment of wet hydrogen sulfide and wires made thereof and their assembly, steel pipes, steel bands and shielding wires for marine cable are disclosed. This steel contains 0.40 to 0.70% of C, 0.1 to 1% of Si, 0.2 to 1% of Mn, up to 0.25% of P and up to 0.010% of S, and further, if necessary, 0.008 to 0.050% of Al and the balance of Fe and unavoidable impurities, and has a spheroidized structure. In addition, a flexible sour fluid transport pipe made of the high-strength steel band having the above-described composition and a tensile strength of 50 to 80 kg/mm.sub.2 is also disclosed.
