ASTM B353
This specification covers seamless and welded wrought zirconium and zirconium-alloy tubes for nuclear application.Nuclear fuel cladding is covered in Specification B 811. Five grades of reactor grade zirconium and zirconium alloys suitable for nuclear application are described.The present UNS numbers designated for the five grades. Unless a single unit is used, for example corrosion mass gain in mg/dm2, the values stated in either inch-pound or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. SI values cannot be mixed with inch-pound values.
