Abstract

1. Method for facilitating the cold-working of stainless steel by the application of an oxalate coating and subsequent thereto of a lubricant, characterised in that the oxalate coating is applied by contact with an oxalating solution which consists of 20 to 100 g/l oxalic acid, 5 to 50 g/l hydroxylammoniumsulphate, 0.3 to 3 g/l water-soluble polymer and 0.1 to 10 g/l sodium thiosulphate, optionally fluoride and/or chloride additives and constituents of the treated stainless steel which dissolve and usual impurities remainder water.
