摘要
This invention provides a high-strength steel wire of excellent fatigue characteristics used for an extrafine steel wire of a high strength and a high ductility, such as a steel cord and a belt cord used to reinforce a rubber and an organic material for the production of a tire, a belt and a hose, and a high-strength steel wire, such as a rope and a PC wire. The present invention is characterized in that it contains 0.7-1 mass % of C, 0.1-1.5 mass % of Si, 0.1-1.5 mass % of Mn, not more than 0.02 mass % of P, not more than 0.02 mass % of S, and Fe and unavoidable impurities for the rest, not less than 80 % of nonmetallic inclusions comprising 4-60 % of CaO + MnO, 22-87 % of SiO2 and 0-46 % of Al2O3, a melting point being not higher than 1500 DEG C.
