Document Type and Number:
WIPO Patent Application WO/2019/017164
Kind Code:
A1
Abstract:
According to the present invention, the contour shape of a cross-section perpendicular to the longitudinal direction of a wire 2 is a circle with a diameter of D. A virtual circle 4 is assumed which is concentric with the circle of the contour shape of the wire 2 and has a diameter that is 3/4 of the diameter D. A first measuring point M1, a second measuring point M2, a third measuring point M3, a fourth measuring point M4, a fifth measuring point M5, a sixth measuring point M6, a seventh measuring point M7, and an eighth measuring point M8 are assumed to be on the virtual circle 4. The Vickers hardnesses at these eight measuring points are measured. The standard deviation σ of the eight measurement values is 10 or less. It is desirable that the average of the eight measurement values be 670-770 inclusive.
