Abstract (en)
[origin: WO03042342A2] The invention concerns a method for working or forming metals which consists in using an aqueous lubricant containing as water-soluble extreme pressure additive, methanesulphonic acid or a water-soluble methanesulphonic acid salt. The water-soluble methanesulphonic acid salt is an alkali or alkaline-earth, ammonium, alkanolamine or ethoxylated fatty amine salt. The inventive aqueous lubricants have good extreme pressure properties and good properties with respect to corrosion.
