Abstract
A heat-resistant alloy spring is made of a Ni-based alloy material comprising in weight %: not more than 0.1% C; not more than 1.0% Si; not more than 1.50% Mn; 13.0 to 25.0% Cr; 1.5 to 7.0% Mo; 0.5 to 4.0% Ti; 0.1 to 3.0% Al; {at least one optional element selected from the group consisting of 0.15 to 2.50% W, 0.001 to 0.020% B, 0.01 to 0.3% Zr, 0.30 to 6.00% Nb, 5.0 to 18.0% Co, and 0.03 to 2.00% Cu}; the balance being essentially Ni; and incidental impurities. The Ni-based alloy material is provided in its crystal structure with gamma prime phase [Ni(Al, Ti)] or gamma prime phase [Ni(Al, Ti, Nb)].
