  • WATER-SOLUBLE LUBRICATING AGENT FOR PLASTIC WORKING, METAL MATERIAL FOR PLASTIC WORKING, AND WORKED METAL ARTICLE
    Publication number: 20150329797
    Abstract: Provided is a water-soluble rubricating agent for plastic working being capable of forming a lubricating film having lubricity and seizure resistance equal to or greater than a phosphorus-containing chemical conversion treatment film, having excellent corrosion resistance, and also having good film adhesion, without including phosphorus in the film. This water-soluble non-phosphorus lubricating agent for plastic working includes an inorganic solid lubricant as component A, a wax as component B, and a water-soluble inorganic metal salt as component C, wherein the mass ratio (component A/component B) of solid content for component A to solid content for component B is 0.1 to 5, and the mass percentage (component C/(component A+component B+component C)) of solid content for component C to total solid content for components A, B and C is 1 to 30%.
    Type: Application
