Abstract
A heat treatment oil composition is provided that suppresses the decrease of luster in a heat treatment of a metal material, and is capable of suppressing the increase of the number of second (characteristic number of second) until reaching the temperature where the vapor blanket stage ends with the lapse of time and the decrease of the kinetic viscosity with the lapse of time. The heat treatment oil composition contains (A) a base oil and (B) a vapor blanket breaking agent selected from one or more of a petroleum resin, a terpene resin, rosin, and derivatives thereof.
