A heat resistant alloy excellent in bending property and ductility after aging, comprising 0.12 to 0.33% (by weight, the same as hereinafter) of C, less than 1.2% of Si, less than 1.5% of Mn, 23 to 25% of Cr, 37 to 40% of Ni, 0.5 to 1.8% of Nb and 0.04 to 0.15% of N, the balance being substantially Fe and unavoidable impurities, with the mutual relationship of C and Si contents represented by the range indicated by hatching in FIG. 1, which may be manufactured into tubes by centrifugal casting, to be used as deformed tubes after bending. |
