Definitions

• Quenching compositions of the above types are defective in a number of respect-s among which are that water or emulsion quenching causes stress and strains in the metal such as steel which results in warping and cracking thereof, rendering the metal unusable.
• Oil quenching although essentially obviating this objectionable characteristic of water or emulsion quenching compositions, tend to leave adherent deposits on quenching metal surfaces which must be removed by relatively expensive butfing or machining operations prior to further processing of the metal. This, plus the fact that oil quenching is expensive and the life of such oil is short because of thermal and oxidation deterioration, thereby requiring continuous replacement with fresh oils, presents a pressing problem to the industry.
• An object of the present invention is an improved process for quenching metals.
• a further object is to provide a quenching oil composition of superior speed and stability.
