ABSTRACT:
A lubricant for non-chip metal forming comprising (1) 5% by weight or more of at least one powdered sulfate selected from the group consisting of calcium sulfate and barium sulfate having a mean particle size of 100 .mu. or less and (2) at least one conventional lubricant selected from the group consisting of inorganic solid lubricants, organic solid lubricants and organic liquid lubricants. This lubricant is excellent in galling resistance (anti-weld property) as well as in other properties required for a lubricant for non-chip metal forming. In the non-chip metal forming using this lubricant, it is sufficient to subject the raw material to a simple pretreatment such as pickling or shot blasting to accomplish the desired non-chip metal forming.
