(57) [Abstract] [Problem] It has excellent work lubrication performance and rust prevention property, and can perform cold forging without phosphorous chemical conversion coating even in severe cold forging such as plastic working of steel or steel alloy. And to provide a cold forging lubricant having excellent film removal properties. SOLUTION: The general formula: (In the formula, R 1 represents a C 10 -C 60 alkyl group, and R 2 and R 3 represent a hydrogen atom, a C 1 -C 8 alkyl group, and the like.) An alkylphosphonic acid derivative represented by, or a derivative of an amine compound, an amino alcohol and a polyamine compound, and a reaction product of the derivative with at least one of a surfactant and a steel or steel alloy characterized by being dispersed in water together with a surfactant. Aqueous cold forging lubricant. |
