Zr-2 Niobium Alloy Bar
The corrosion resistance of Zr-2.5 Nb alloys is highly dependent on heat treatment. The quench-age corrosion rate of Zr-2.5 Nb alloys is higher than that of Zr-2 alloys.
Description
The Zr-2 alloy was first used on the first U.S. nuclear submarine in 1955, and after more than 20 years of practice, it has proven to be a reliable reactor as a fuel element cladding material and pressure tube material for both boiling water and pressurized water reactors. .
In order to improve the PCI resistance of Zr-2 alloy, the United States has developed Zr-2 tube lining technology with a pure zirconium layer thickness of 80-100μm.
Zr-2 alloy is generally used in the manufacture of boiling water reactors.
Products Description
The corrosion resistance of Zr-2.5 Nb alloys is highly dependent on heat treatment. The quench-age corrosion rate of Zr-2.5 Nb alloys is higher than that of Zr-2 alloys. It is higher than that of CO2 and air. Zr-2.5Nb does not differ much from Zr-2 after long-term corrosion (i.e., 30 years) in aqueous media (i.e., corrosion between 316-400°C). The corrosion resistance of Zr-2.5Nb (including the cold-worked condition with increasing corrosion temperature) is superior to that of Zr-2.
