Abstract:
A method for working or forming metals which consists in usings an aqueous lubricant containing as water-soluble extreme pressure additive, methanesulphonic acid or water-soluble methanesulphonic acid salt. The water-soluble methane sulphonic acid salt is an alkali or alkaline-earth, ammonium, alkanol amine or ethoxylated fatty amine salt. The inventive aqueous lubricants have good extreme pressure properties and good properties with respect to corrosion.
