Abstract

A low-carbon resulfurized free-cutting steel material which contains less than 0.05% C, less than 0.05% Si, 0.7-2.2% Mn, 0.03-0.20% P, 0.40-0.70%, excluding 0.40% and 0.70%, S, less than 0.005% Al, 0.0050-0.0380% O, and 0.0020-0.0250% N, with the remainder being iron and impurities, wherein Ca, Mg, Ti, Zr, and REM among the impurities satisfy the following relationships: Ca < 0.001%, Mg < 0.001%, Ti < 0.002%, Zr < 0.002%, and REM < 0.001%, provided that 0.010 < O/S < 0.080 and 2.5 < Mn/(S+O) < 4.0. When cut with a high-speed steel tool, the steel material has the same chip disposability as conventional Pb-free free-cutting steel materials and even has better finished-surface properties than that. It is excellent also in continuous castability and hence suitable for mass production. This material may contain at least one of Te ≤ 0.05%, Bi ≤ 0.15%, and Se < 0.30%.
