Tubes made of Nb-stabilised 25%Cr35%Ni iron-based superalloys have been extensively used in the radiant sections of naphta cracking furnaces where ethylene production is done. Since the tubes are generally replaced before reaching their design lives of 100000 hrs for such systems realistic remaining life predictions become essential for economy and safety.
