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.
