Abstract
A bright rolled metal strip product having a surface that contains multiple microscopic raised prows formed by partial back extrusion of strip material into smooth, bowl-shaped depressions provided in a work roll surface. The prows are formed by smearing of the strip surface that results from the relative velocities of the strip and work rolls that occurs when massive reductions are taken in the thickness of the strip by the work rolls.
