  • Method for preparing shaped metal bodies for cold working
    Patent number: 10392705
    Abstract: Methods for treatment shaped bodies are described herein. The methods generally include contacting at least one shaped body with an aqueous acidic composition to form a conversion layer on a surface of the at least one shaped body, wherein the surface includes iron or steel and a carbon content in a range of 0 to 2.06 wt. % and a chrome content in a range of 0 to <10 wt. % and wherein the surface is optionally galvanized or alloy galvanized. The aqueous acidic composition includes water; from 2 to 500 g/L oxalic acid; and from 0.01 to 20 g/L of at least one catalyst based on guanidine, nitrate or combinations thereof, wherein a pickling removal of the aqueous acidic composition is in a range of 1 to 6 g/m2.
