Abstract
Abstract Lubricants useful in metal working processes, especially drawing, comprise an oil of lubricating viscosity; a carboxylic acid or derivative thereof, especially an anhydride of a hydrocarbon-substituted succinic acid in which the substituent contains about 6-30 carbon atoms; and a phosphorus acid salt, usually a zinc salt of a phosphorodithioic acid. The lubricant may also contain other ingredients, especially chlorinated wax or mixtures of aliphatic alcohols and hydrocarbons. Said lubricant provides improved lubricity, corrosion resistance, cleanability, anti-wear properties and extreme pressure properties when used in the working operation.
