摘要： An oil-tempered wire that has high fatigue strength and toughness after the nitriding treatment, and a method of producing the same, and a spring using the oil-tempered wire are provided. The oil-tempered wire has a tempered martensite structure. A lattice constant of a nitride layer formed on a surface of the wire is 2.870 Å to 2.890 Å when the oil-tempered wire is nitrided. The oil-tempered wire is produced by wire drawing a steel wire and quenching and tempering the wire drawn steel wire. The quenching is performed after the radiation heating is performed at 850 to 950° C. for over 30 sec to 150 sec, and the tempering is performed at 400 to 600° C.

摘要： A steel wire (e.g., a piano wire) for use in a stringed musical instrument is designed to have a specific chemical composition in which phosphorus content ranges from 0.015 weight percent to 0.050 weight percent, wherein the total decarburized layer depth of a decarburized layer formed on the surface, which is subjected to decarburized depth measurement using a microscope method as defined in the Japanese Industrial Standard JIS G 0588, is reduced to 2 μm or less. Other chemical substances included in the chemical composition of the steel wire are preferably defined in the standard JIS G 3502 regarding chemical compositions of piano wires. In manufacturing, a rolled steel material is subjected to wire drawing and patenting under prescribed conditions, wherein the sound quality realized by the steel wire installed in a stringed musical instrument can be noticeably improved by adopting both chemical composition control and total decarburized layer depth control.
