PROBLEM TO BE SOLVED: To provide a saw wire capable of improving slice cutting efficiency. SOLUTION: The saw wire has the following features. The hardness HD of the surface layer part from the outer surface to the depth of 10μm is≥800 Hv in Vickers hardness. The residual stress IS of the surface layer part from the outer surface to the depth of 10μm is on the compression side. The minimum value of an absolute value of the stress is≥10 kg/mm<SP>2</SP>. The tensile strength TS satisfies the following formula (1) calculated from a diameter (d). Here, the above formula (1) is expressed as TS≥-2,000d+4,200 (MPa). COPYRIGHT: (C)2005,JPO&NCIPI |
