In the cold drawing of steel tubing, an excellent lubrication which permits drawing the tubing while retaining its original metallic luster can be achieved by first contacting the surfaces of the tubing, both exterior and interior, with a colloidal titatium containing aqueous composition, drying the tubing, and then applying to the surface of the tubing a liquid lubricating composition comprising (i) from 40 to 95 % of a first component selected from the group consisting of olefin/oil or olefin/fat compounds which contain from 23 to 30 % of sulfur and olefin/higher ester compounds which contain from 23 to 30 % sulfur, including mixtures of two or more chemical species meeting this description; and (ii) from 5 to 50 % of a second component selected from the group consisting of oil soluble polymer compounds, fats and oils, synthetic oils, mineral oils, higher fatty acids, and the amine salts of higher fatty acids. |
