Abstract: The finite element(FE)method is used to simulate the deformation courses of three different deformation processes for the small-sized UNS N08825 inconel seamless steel tube,based on which,relevant elements associated with the cold-drawing process are analyzed,including distributions of the stress,the strain and the metal flow speed,and the changes of wall thickness before and after the cold-drawing process,and the cold drawing load is predicted.Combined the simulation result with the site production experience,the most suitable deformation process path is determined.
