Abstract
Abstract An improved quenching oil composition comprising a major amount of a quench oil of lubricating viscosity; a minor amount of at least one carbon linked poly-phenate metal compound sufficient to improve the anti-staining properties of the composition and at least one naphthyl amine sufficient to improve the resistance to oxidation of the composition. The compositions may also include a minor amount of at least one of certain diamine components to provide further improved oxidation resistance. An improved method for quenching is also disclosed.
