Method for forming a hollow of a ferritic FeCrAl alloy into a tube
The present invention relates to a method for forming a hollow 26 of a ferritic FeCrAl alloy into a tube 2. While tubes made of powder metallurgical, dispersion hardened, ferritic FeCrAl alloys are commercially available, hollows made of FeCrAl alloys so far can hardly be formed into tubes of small dimensions. The major reason for the problems in forming hollows of a ferritic FeCrAI alloy into a finished product is that FeCrAl alloys are brittle. It is therefore an aspect of the present invention to provide a tube 2 made of a ferritic FeCrAl alloy having arbitrary small dimensions. Furthermore, it is an aspect of the present invention to provide a machine 1 and a method for forming a tubular hollow 26 into a finished tube 2 of a ferritic FeCrAl alloy. At least one of the above aspects is addressed by a method for forming a hollow into a tube 2 comprising the steps providing the hollow 26 of a ferritic FeCrAl alloy, heating the hollow 26 to a temperature in a range from 90° C. to 150° C., and forming the heated hollow 26 by pilger milling or drawing into the tube.
