Abstract
The invention relates to a tube, bar, sheet or strip resistant both to uniform and nodular corrosion, of a zirconium-base alloy of a composition (% by weight) of Fe 0.1 to 0.35, V 0.07 to 0.4, Q 0.05 to 0.3, Sn below 0.25, Nb below 0.25, trace impurities and balance Zr. The invention also relates to a process for producing these products which have a greatly increased service life. It also relates to composite tube having an internal and/or external alloy sheathing.
