Scope

15.1 For the purpose of determining compliance with the specified limits for requirements of the properties listed in the following table, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding methods of Practice E29.

Property	Rounded Unit for Observed or Calculated Value
8199;Chemical composition, and tolerances (when expressed as decimals)	nearest unit in the last right-hand place of figures of the specified limit
8199;Tensile strength and yield strength	nearest 1000 psi (10 MPa)
8199;Elongation	nearest 18201;%

1.1 This specification covers hot- or cold-worked hafnium rod and wire.

1.2 This specification contains two material grades, one specifically for nuclear applications (Grade R1) and one for commercial alloying applications (Grade R3).

1.3 The products covered include the following:

1.3.1 Rod ³/₈ to 1 in. (9.5 to 25 mm) in diameter.

1.3.2 Wire less than ³/₈ in. (9.5 mm) in diameter.

1.4 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.

1.5 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.
