PURPOSE:To drastically reduce the incident of extra fine cutting scraps, by specifying the constitution of steel as well as the chemical components of said steel. CONSTITUTION:Said wire rod for production of steel wool has the basic components, by wt%, of 0.03-0.25 C, 0.005-0.30 Si, 0.2-1.5 Mn, 0.0005-0.0035 Ca, <=0.12 P, <=0.02 S, 0.003-0.012 N and 0.003-0.03 O, contains at need 0.0003-0.0030 B, and furthermore has the constitution of bainite or the mixed constitution of the bainite and ferrite. In this way, the incidence of the extra fine cutting scraps can be drastically reduced by controlling the constitution of the wire rod as well as the chemical components of the same. The improvement of a yield and the improvement of working environment can be thus attained in the production of the steel wool.
