ASTM B350/B350M-11(2016)e1

Standard Specification for Zirconium and Zirconium Alloy Ingots for Nuclear Application

ABSTRACT
This specification covers vacuum-melted zirconium and zirconium alloy ingots for nuclear application. Materials covered shall be produced by multiple vacuum arc melting, or electron beam melting, or other melting processes conventionally used for reactive metals. Unless otherwise specified, ingots shall be conditioned by machining or grinding or both to remove surface and subsurface defects detrimental to subsequent fabrication. The ingot shall conform to the chemical composition requirements prescribed. The ingots shall be analyzed for the alloying and impurity elements prescribed. Ingots shall be inspected ultrasonically using the prescribed methods. The test shall be conducted in accordance with practice E 114.
SIGNIFICANCE AND USE
10.1 For purposes of determining compliance with the specified limits for requirements of the properties listed in Table 1 and Table 2, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E29.
SCOPE
1.1 This specification covers vacuum-melted zirconium and zirconium alloy ingots for nuclear application.  
1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.  
1.3 The following precautionary caveat pertains only to the test method 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.

6. Materials and Manufacture
6.1 Materials covered by this specification shall be produced by multiple vacuum arc melting, or electron beam melting, or other
melting processes conventionally used for reactive metals; all melting is to be carried out in furnaces usually used for reactive
metals.

7.1 Unless otherwise specified, ingots shall be conditioned by machining or grinding or both to remove surface and subsurface
defects detrimental to subsequent fabrication.
7.2 After conditioning has been completed, no abrupt changes in diameter or local depression that will impair subsequent
fabrication shall be permitted. The difference between the maximum and minimum radii of the conditioned ingot shall not exceed
20 % of the maximum radius. Lands, grooves, and local depressions shall be blended to a maximum angle of 30° to the axis of

8. Chemical Requirements
8.1 The ingot shall conform to the requirements for chemical composition as prescribed in Table 1. Guide E2626 may be used
as a guide for chemical analysis techniques.
NOTE 2—Nuclear grade zirconium ingots produced from electrolytic starting material should be produced using methods such that the final ingot
