PURPOSE: A wire for wire drawing which has an excellent wire drawing property with high surface lubrication is provided to form a self-lubrication layer without any special coating on the surface of a steel material by including antimony.;CONSTITUTION: A wire for wire drawing which has an excellent wire drawing property is composed of, in wt%: C: 0.25-0.45; Si: 0.1-0.2; Mn: 0.1-0.7; Sb: 0.005-0.02; and the remainder Fe and inevitable impurities. The wire for wire drawing includes Sb oxide inside. The internal structure of the wire for wire drawing is composed of ferrite and pearlite, and the grain size of the ferrite is 20μm or less. A wire drawing method comprises the following steps of: preparing the wire for wire drawing; heating the wire at the temperature of 300-400°C; and drawing the wire.;COPYRIGHT KIPO 2013
