Another alloy has substantially the same composition as described above except that the Cr content is 10 to 20% and the (A1 + Ti) content and the (W + 1/2Mo) content are within the range surrounded by the line connecting the points A, B, C, F, G, H and E in Fig.1. The alloys are useful as a material for a gas turbine or other structural parts to be exposed to high temperatures because of their high high- temperature strength and good weldability.
