- Scope
For the purposes of determining compliance with the specified limits for requirements of the properties listed in this specification, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E29.
1.1 This specification covers five grades of wrought niobium and niobium alloy strip, sheet, and plate as follows:
1.1.1 R04200-Type 18212;Reactor grade unalloyed niobium,
1.1.2 R04210-Type 28212;Commercial grade unalloyed niobium,
1.1.3 R04251-Type 38212;Reactor grade niobium alloy containing 1 % zirconium, and
1.1.4 R04261-Type 48212;Commercial grade niobium alloy containing 1 % zirconium.
1.1.5 R04220-Type 58212;RRR grade pure niobium.
Note 18212;This grade of niobium is used in superconducting applications that require the ultra high purity. Because of the high purity the product is conducive to very large grains that can adversely affect formability. It is not recommended for other applications.
1.2 Except for dimensional tolerances in Table 1, the values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 The following precautionary caveat pertains only to the test methods portion 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.
