In the figure, σ max and σ min represent the maximum and minimum stresses in the die, respectively, corresponding to maximum and minimum load provided the die is not pre-stressed which is the case in hot extrusion dies. Pre-stressing is usually provided in cold...

..., it is not practical to hot extrude thin wall tubes beyond a specified limit. Drawing is an easier and less expensive process than extrusion; therefore, a thick wall tube is cold extruded and finished on a draw bench or pilger mill. The drawing process is essentially a tensile process. Microcracks and other defects...
