PROBLEM TO BE SOLVED: To provide a non-graphite type lubricant that realizes lubricity and releasability comparable to those of a graphite-based lubricant. SOLUTION: (A) An alkali metal salt of an aromatic carboxylic acid compound having two or more carboxyl groups, (B1) a water-soluble polymer compound having a molecular weight of 5,000 to 100,000, and (B2) a molecular weight of 100,000. A lubricant composition for warm and hot plastic working, comprising a water-soluble polymer compound that is more than 500,000 and less and (C) water. [Selection] No figure |
