PURPOSE: To provide bainitic wire rod or steel wire excellent in wire drawability and to provide the manufacturing method thereof.
CONSTITUTION: The bainitic wire rod or steel wire for wire drawing has characteristics of having a compsn. contg., by weight, 0.70 to 1.20% C, 0.30 to 0.90% Mn and 0.15 to 1.00% Si, contg., as alloy components, one or two kinds of 0.006 to 0.100% Al and 0.01 to 0.35% Ti, contg., at need, 0.10 to 0.50% Cr, in which each content of P and S is limited to ≤0.02% and ≤0.01%, and the balance Fe with inevitable impurities as well as having tensile strength and reduction of area prescribed by the following inequalities (1) and (2): TS≤85×(C)+60... (1) and RA≥-0.875×(TS)+158... (2); where C: carbon content (wt.%), TS: tensile strength (kgf/mm2) and RA: reduction of area (%).
