The present disclosure relates to a method for straightening of a tube comprising a ferritic FeCrAI-alloy. One reason for the challenges regarding the cold working of a hollow of a ferritic FeCrAI-alloy into a finished tube is that FeCrAI-alloys have a low ductility. Even if a tube of a FeCrAI-alloy is obtained by cold working a hollow into a tube, the tube can hardly be straightened. This is even more a problem if a tube obtained is annealed, wherein the annealing leads to a deformation of tube along the longitudinal direction of the tube. Therefore, there is a need for a method for straightening of a tube comprising a ferritic FeCrAI-alloy. Thus, according to the present disclosure a method for straightening of a tube is suggested, wherein the method comprises the steps of providing a tube comprising a ferritic FeCrAI-alloy, heating the tube, and straightening and forming the heated tube by stretching.
