The manufacturing process chain for extrusion of AISI 316L tubes is simulated using the finite element method. Models of induction heating and expansion is included and the temperature field in the billet before extrusion is calculated. It is shown that a correct initial temperature of the billet is needed in order to predict the extrusion force curve in the initial stage of the process.
