Abstract

Procedure for the preparation of steel parts for cold forming without chip removal, characterized in that the grease-free parts to be shaped are successively subjected to the following treatments: a) pickling in a mineral acid, mainly sulfuric acid or hydrochloric acid; b) rinse with water; o) pre-rinse in an aqueous suspension with 0.1 to 8 g/l of secondary and/or tertiary manganese phosphate, with eventual addition of 0.1 to 5 g/l of one or more condensed alkali metal phosphates; d) phosphated by an aqueous solution of manganese phosphate or manganese-iron; e) rinse with water; f) if necessary, rinse with a weakly alkaline solution; g) soaping with an aqueous soap-type lubricant containing one or more alkali metal or amine soaps dissolved together with a hardly soluble, dispersed metal soap; h) drying the soap film.
