Abstract: PROBLEM TO BE SOLVED: To provide a Cr-base heat-resisting alloy usable, e.g. as a material for moving and stationary blades of a gas turbine, having high-temperature strength equal to or higher than that of an Ni-base alloy and also having excellent room-temperature ductility. SOLUTION: The Cr-base heat-resisting alloy has a composition composed essentially of Cr and containing 1-40 atomic % of either of Re and W or a mixture thereof.
