ABSTRACT:
A blanking solution containing surfactants, corrosion inhibitors, and optionally biocides and antifoam agents can be applied to steel blanks in a stamping or drawing mill to prevent the transfer of solid film prelube lubricants from the steel blanks to the transfer rolls in the mill. The surfactant is preferably a nonionic surfactant which does not have any essential effect on the coefficient of friction when the prelubed steel blanks are stamped or drawn to form the final part.
