ABSTRACT:
A zirconium alloy that has sufficient corrosion resistance, strength and stress relaxation property for use as a component of a pressurized water nuclear reactor fuel assembly is disclosed. This alloy consists essentially of 0.2 to 0.91% Sn, 0.18 to 0.6% Fe, 0.07 to 0.4% Cr, one or both of 0.05 to less than 0.5% and 0.01 to 0.2% Ta, one or both of 0.05 to 1% V and 0.05 to 1% Mo, with the balance being Zr and incidental impurities, all percentages being based on weight.
