Our Zr-2.5Nb sheet, Zr-2.5Nb bar, Zr-2.5Nb foil, Zr-2.5Nb wire, Zr-2.5Nb tube, Zr-2.5Nb target and Zr-2.5Nb parts all follow ASTM B351, ASTM B352 and ASTM B353.
The corrosion resistance of Zr-2.5Nb alloy has a great relationship with heat treatment. The corrosion rate of Zr-2.5 Nb alloy with quenching aging is higher than that of Zr-2 alloy. It is higher than that in CO2 and air. Zr-2.5Nb is little different from Zr-2 in the medium of water after long-term corrosion (i.e., 30 years) (i.e., the corrosion between 316-400˚C).The corrosion resistance of Zr-2.5Nb (including cold - processing state) is better than that of Zr-2 as the corrosion temperature increases.
