During the hot piercing phase of seamless tube production, friction and contact conditions between tools workpiece significantly influence final product quality energy consumption. The effects on production high alloyed steels like Super Cr13 steel are critical. This study analyses effect different at workpiece-tool interface in bars to minimize total consumption such a manufacturing process. For this purpose, three-dimensional finite element method (FEM) is employed simulate analyze variety (plunge, rollers, Diescher disks) lead differences applied stress areas. Consequently, various models coefficients were selected for interfaces. relation strain rate, temperature, geometry pierced discussed, with power presented. Experimental tests have been used FEM validation result analysis, finally, most effective lower
