The deterioration resistance of three marquenching oils (one imported and two home products), were compared by measuring their various physical properties and cooling ability. These measurements were carried out on fresh and deteriorated samples under the exactly same conditions by an electric-resistance heater immersed in each. In the measurement of the cooling ability a carbon tool steel and a bearing steel were used as specimens, and after the marquenching, the depth of hardening in constant size specimens and the critical diameter in variable size specimens were determined. It was found that, among these oils, one of the home products is superior to others in cooling ability and particularly in stability against deterioration.
