Abstract
A low-carbon sulphur free-cutting steel which contains C: 0.02% to less than 0.20%, Si: more than 0.10% to 1.5%, Mn: 0.8 to 2.2%, P: 0.005 to 0.25%, S: more than 0.40% to 0.8%, O: <0.010%, N: ≤ 0.025%, and Ca: 0.0003 to 0.005% with the balance consisting of Fe and impurities and in which the impurities contain Al < 0.005%, Mg < 0.0003%, Ti ≤ 0.002%, Zr ≤ 0.002%, and REM < 0.0003% and the relationships: 2.0 < Mn/S < 4.0, and 0.0005 ≤ 10Ca x Si ≤ 0.050 are satisfied attains a smaller finished-surface roughness than that of conventional non-Pb low-carbon free -cutting steel and excellent chip disposability in the finish cutting process by turning with a carbide tool. The low-carbon sulphur free-cutting steel may contain one or more of Te≤0.05%, Bi≤0.15%, and Sn≤0.5% and/or one or more of Cr≤2.0%, Mo≤0.5%, V≤0.3%, and Nb≤0.3%.
