Abstract

An induction-hardening steel having the following chemical composition, in mass%: C=0.45-0.85%; Si=0. 01-0.80%; Mn=0.1-1 .5%; Al=0.01-0.05%; REM=0.0001-0.050%; 0=0.0001-0.0030%; Ti=less than 0.005%; N=0.015% or less; P=0.03% or less; S=0.01% or less; and with iron and impurities constituting the remainder. Further contained therein i s a composite inclusion containing REM, O , S and Al, and having TiN adhered thereto. The induction-hardening steel is characterized in that the total of the number density of MnS having a maximum diameter of IOµπɩ or more, and the number density of TiN having a maximum diameter of Iµπɩ or more and independently present and not adhered to the inclusion, is 5/mm 2 or less.
