Abstract: 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 titanium 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.

Abstract: A lubricant composition effectively enhancing the press-formability, and corrosion-resistance of a zinc-plated steel material and providing a superior, anti-powdering property and degreasing comprises (A) 70 -97% by weight of a lubricant component comprising the sub-components of (a) a succinate of a C.sub.12-18 aliphatic alcohol, (b) a paraffin wax with a melting point of 45.degree. C. -55.degree. C. and (c) a C.sub.12-18 fatty acid ester of C.sub.6-10 aliphatic alcohol and/or a mineral oil, the weight ratio ((a)+(b))/(c) being 1/3 to 1/1 and the weight ratio (a)/(b) being 1/3 to 4/1, and (B) 3 to 30% by weight of a rust-inhibiting component comprising a sulfonates with C.sub.16 or more, a carboxylic acid with C.sub.12 or more and/or a salt of the carboxylic acid, and has a melting point of 25.degree. C. to 40.degree. C. and an acid value of less than 2.0.

Abstract: An aqueous lubrication treatment liquid for a cold plastic working of a metallic material comprises 50 to 400 g/l of a solid lubricant, for example, MoS.sub.2, 1 to 40 g/l of a surfactant, 10 ppm to 5000 ppm, in terms of colloidal titanium compound, water, and optionally, 5 to 150 g/l of a binder and 4 to 160 g/l of a metallic soap. This liquid exhibits a strong bonding to the metallic material and an excellent lubricating property, and prevents rusting of the metallic material.

Abstract: Iron and steel articles to be subjected to a cold forming operation are treated with a phosphatizing solution to form a zinc phosphate film on the surface, which film contains from about 5 to 80% by weight of the total film of zinc calcium phosphate. Thereafter, a soap type lubricant coating is applied to the zinc phosphate film. Preferably, the zinc phosphate film is formed on the surface by treating it with a phosphatizing solution which comprises from about 0.1 to about 0.35% by weight calcium ion, from about 0.1 to about 1.5% by weight zinc ion, from about 0.5 to about 3.0% by weight PO.sub.4, and from about 3.0 to about 5.0% by weight nitrate ion, which solution has a weight ratio of calcium ions:zinc ions of about 0.1-1.0:1 and a weight ratio of nitrate ions:PO.sub.4 of about 1.0-5.0:1. One or more of nickel, copper or cobalt ions may also be included in the phosphatizing solution in a total amount of from about 0.01 to about 0.2% by weight of the solution.

Abstract: A chromium-free treatment for aluminum imparts corrosion resistance and paint receptivity to the surface. The process is sequential and includes a first contact with an aqueous alkaline solution (pH above 10) containing complexed iron ion, water rinsing, and then contact with an aqueous acidic organic tannin-containing composition.

Abstract: Disclosed is a composition and method for its use to improve the corrosion resistance of conversion-coated metal surfaces. The composition contains a myo-inositol phosphate ester or soluble salt thereof and is applied as a rinse of the conversion coating.
