Zircon-based alloy with increased resistance to corrosion by nitric acid and with good creep resistance.

摘要

A zirconium alloy which has good creep strength and bending properties as well as improved corrosion resistance in nitric acid solutions of low, medium, and high concentrations and which can withstand stress corrosion cracking in highly concentrated nitric acid solutions even under a high anodic potential is disclosed. The zirconium alloy consists essentially of, by weight percent: one or both of Ti: 5.0 - 30% and Ta: 1.0 - 20%, Fe: not greater than 0.3%, Cr: not greater than 0.1%, Oxygen: 0.05 - 0.2%, N : not greater than 0.05%, H : not greater than 0.01%, one or more of W, V, and Mo: 0 - 3.0% in total, and the balance Zr and inevitable impurities.
