Die arrangement for use with conventional and hydrostatic extrusion presses consisting of a first die for providing a first extruded section of a billet and a second die cooperating with the first die to further extrude said first extruded section to final shape. Successive dies beyond the second die are contemplated to provide successive step-wise extrusion for greater reductions, especially of large billets. The method of the invention comprises step-wise incremental sequential extrusion of the billet and extruded portions of the billet until the final shape is achieved.
