1、Designation: B 350/B 350M 02 (Reapproved 2006)Used in USNRC-RDT standardsStandard Specification forZirconium and Zirconium Alloy Ingots for NuclearApplication1This standard is issued under the fixed designation B 350/B 350M; the number immediately following the designation indicates the yearof origi
2、nal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers vacuum-melted zirconium andzirconium
3、alloy ingots for nuclear application.1.2 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard. Within the text, theSI units are shown in brackets. The values stated in eachsystem are not exact equivalents; therefore, each system shallbe used independently
4、 of the other. Combining values from thetwo systems may result in nonconformance with the specifi-cation.1.3 The following precautionary caveat pertains only to thetest method portions of this specification: This standard doesnot purport to address all of the safety concerns, if any,associated with
5、its use. It is the responsibility of the user of thisstandard to establish appropriate safety and health practicesand determine the applicability of regulatory limitations priorto use.2.

15、uirements (Table 1).6. Materials and Manufacture6.1 Materials covered by this specification shall be pro-duced by multiple vacuum arc melting, or electron beammelting, or other melting processes conventionally used forreactive metals; all melting is to be carried out in furnacesusually used for reac
16、tive metals.7. Condition7.1 Unless otherwise specified, ingots shall be conditionedby machining or grinding or both to remove surface andsubsurface defects detrimental to subsequent fabrication.7.2 After conditioning has been completed, no abruptchanges in diameter or local depression that will impa
17、irsubsequent fabrication shall be permitted. The differencebetween the maximum and minimum radii of the conditionedingot shall not exceed 20 % of the maximum radius. Lands,grooves, and local depressions shall be blended to a maximumangle of 30 to the axis of the ingot. Each end of the ingot shallbe
18、chamfered or radiused. The minimum chamfer or radiusshall be12 in. 12 mm.8. Chemical Requirements8.1 The ingot shall conform to the requirements for chemi-cal composition as prescribed in Table 1.8.2 The ingot shall be sampled in sufficient places along theside wall so that the top sample is within
19、5 in. 125 mm of thetop face and the distance between samples or between thebottom face and a sample does not exceed one ingot diameter.A minimum of three samples per ingot is required.8.3 These samples shall be analyzed for the alloying andimpurity elements given in Table 1.8.4 Analysis shall be mad
20、e using the manufacturers stan-dard methods. In the event of disagreement as to the chemicalcomposition of the metal, methods of chemical analysis forreference purposes shall be determined by a mutually accept-able laboratory.8.5 Product Check AnalysisProduct check analysis is ananalysis made by or
21、for the purchaser for the purpose ofverifying the composition of the ingot. The check analysistolerances reflect the variation between laboratories in themeasurement of chemical composition. The permissible varia-tion in the product check analysis from the specified range is asprescribed in Table 2.
22、9. Retest9.1 If any sample or specimen exhibits obvious contamina-tion, improper preparation, or flaws disqualifying it as arepresentative sample, it shall be discarded and a new sampleor specimen substituted.9.2 If the results of any test are not in conformance with therequirements of this specific
23、ation, the ingot may be retested atTABLE 1 Chemical RequirementsElementComposition, Weight %UNS R60001 UNS R60802 UNS R60804 UNS R60901 UNS R60904Tin . 1.201.70 1.201.70 . .Iron . 0.070.20 0.180.24 . .Chromium . 0.050.15 0.070.13 . .Nickel . 0.030.08 . . .Niobium (columbium) . . . 2.402.80 2.502.80O
