PURPOSE: To obtain a Zr alloy for nuclear reactor fuel clad pipe excellent in corrosion resistance, by specifying a composition consisting of Sn, Fe, Cr, Nb, and Zr and also by limiting N content among inevitable impurities.
CONSTITUTION: The Zr alloy has a composition which consists of, by weight, 0.2W1.15% Sn, 0.18W0.24% Fe, 0.07W0.13% Cr, 0.05W1% Nb, and the balance Zr with inevitable impurities and in which amount of N as an inevitable impurity is regulated to ≤60ppm. This alloy shows superior corrosion resistance particularly under the conditions to which nuclear reactor fuel clad pipes are exposed, so that it enables long-period of use as the above clad pipes. In the above Zr alloy, corrosion resistance is deteriorated if any of the quantities of the above constituents deviates from the above compositional range.
