An investigation was conducted of the effect of melting and fabrication variables on the corrosion of Zircaloy-2 in 750 deg F steam at 1500 psi. Two 12 in. diameter production-type ingots and three 4 in. diameter laboratory type ingots were produced representing primary and secondary melting in 75% H--25% Ar atmosphere, primary melting in 75% He-25% Ar and secondary melting in vacuum, and primary and secondary melting in vacuum. Variations were performed in the ingot forging procedures, hot rolling temperatures, homogenization treatment and final heat treatment of the hot rolled Zircaloy-2 strip. Corrosion data were obtained on the strip produced from the large ingots after intervals of were obtained on strip produced from the small ingots at 14 and 28-day intervals. (auth)
