Abstract:
An aqueous heat treatment liquid composition exhibiting a favorable rust resistance with a high cooling capability and a high uneven-cooling resistance is provided. The aqueous heat treatment liquid composition contains a hyperbranched polyglycerol. A mass average absolute molecular weight of the aqueous heat treatment liquid composition is preferably in a range of 5,000 to 500,000. When the aqueous heat treatment liquid composition is used for quenching of a metallic component, the aqueous heat treatment liquid composition can exhibit a favorable rust resistance with a high cooling capability and a high uneven-cooling resistance.
