Abstract:

This specification covers three grades of zirconium and zirconium alloy bar and wire as grade R60702, unalloyed zirconium; grade R60704, zirconium-tin; and grade R60705, zirconium-niobium. The chemical composition; and mechanical properties requirements, such as tensile strength, yield strength, and elongation; are detailed.

Scope:

1.1 This specification covers three grades of zirconium and zirconium alloy bar and wire.

1.2 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.

1.3 The following precautionary caveat pertains only to the test methods portions of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
