(Specification)Standard Specification for Zirconium and Zirconium Alloy Sheet, Strip, and Plate for Nuclear Application
Standard Specification for Zirconium and Zirconium Alloy Sheet, Strip, and Plate for Nuclear Application
ABSTRACT
This specification covers hot- and cold-rolled zirconium and zirconium alloy sheet, strip, and plate.
SCOPE
1.1 This specification covers hot- and cold-rolled zirconium and zirconium alloy sheet, strip, and plate.
1.2 One unalloyed and three alloys for use in nuclear applications are described.
1.3 The products covered in this specification include the following forms and sizes:
1.3.1 Sheet, 24 in. [600 mm] or more in width; under 0.187 in. [4.8 mm) in thickness,
1.3.2 Strip, less than 24 in. [600 mm] in width; under 0.187 in. [4.8 mm] in thickness, and
1.3.3 Plate, over 10 in. [250 mm] in width; 0.187 in. [4.8 mm] and over in thickness.
Note 1: Material over 0.187 in. [4.8 mm] in thickness and less than 10 in. [250 mm] wide is covered as bar in Specification B351/B351M.
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 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.

1.4 Unless a single unit is used, for example corrosion mass gain in mg/dm , 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.

When a sub-size specimen is used, the gauge length shall be as specified in Test Methods E8/E8M for that specimen.
B
“RT” represents room temperature; Note 4 in Test Methods E8/E8M indicates that RT shall be considered to be 50 to 100°F [10 to 38°C] unless otherwise specified.
Paragraph 9.4.4 in Test Methods E21 states that for the duration of the test, the difference between the indicated temperature and the nominal test temperature is not to
exceed ±5°F [3°C] for tests at 1800°F [1000°C] and lower, and ±10°F [6°C] for tests at higher temperatures.
5. Materials and Manufacture
5.1 Materials covered by this specification shall be produced in accordance with Specification B350/B350M; all processes to
be done in furnaces usually used for reactive metals.
6. Condition
6.1 Sheet, strip, or plate shall be furnished in one of the following conditions as designated on the purchase order:
Form Condition
Sheet hot-rolled
hot-rolled, annealed
cold-rolled, annealed
cold-rolled, annealed, followed by a final light cold-
rolled pass, generally on polished rolls.

7. Chemical Composition
7.1 The material shall conform to the requirement for chemical composition as prescribed in Table 1.
7.2 The analysis of the material produced to this specification shall be the one made by the manufacturer on the ingot in
accordance with Specification B350/B350M. This analysis can be performed by the manufacturer on the ingot itself, or on
intermediate or final products with the same frequency and in the same positions relative to the ingot as required in Specification
B350/B350M. The chemical analysis of hydrogen, oxygen, and nitrogen shall be determined on the finished product.
7.3 Analysis shall be made using the manufacturer’smanufacturer’s standard methods. In the event of disagreement as to the
chemical composition of the metal, methods of chemical analysis for reference purposes shall be determined by a mutually
acceptable laboratory.
7.4 Product Analysis—Product analysis is an analysis made by the purchaser or the manufacturer for the purpose of verifying
the composition of the lot. The product analysis tolerances reflect the variation between laboratories in the measurement of
chemical composition. The permissible variation of the product analysis from the specified range is as prescribed in Table 3.
7.5 Number of Tests—Two random samples for each 4000 lb [1800 kg] or fraction thereof shall be analyzed for hydrogen,
nitrogen, and oxygen.
8. Mechanical Properties
8.1 The material shall conform to the requirements prescribed in Table 2 for longitudinal room-temperature mechanical
properties. Transverse and elevated temperature properties shall be used to determine compliance only when specified in the
purchase order. When material is ordered in a condition other than those given in Table 2, the specimens shall be heat treated as
referenced in Table 2 prior to test.

8.2 The yield strength shall be determined by the offset method using 0.2 % criterion as prescribed in Test Methods E8/E8M.
8.3 The tensile properties shall be determined using a strain rate of 0.003 to 0.007 in./in. [mm/mm]/min through the yield
strength. After the yield strength has be exceeded, the cross head speed should be increased to approximately 0.05 in./in.
[mm/mm]/min to failure.
8.4 The tensile properties shall be determined in accordance with Test Methods E8/E8M or E21.
8.5 Number of Tests—For each lot, two random samples for each 4000 lb [1800 kg] or fraction thereof shall be tested for
mechanical properties.
9. Corrosion Properties
9.1 Two samples chosen at random from each 4000 lb [1800 kg] or fraction thereof shall be corrosion tested in steam at 750°F
[399°C], 1500 psi [10.3 MPa] for 72 h or 336 h at the option of the manufacturer in accordance with Test Method G2/G2M.
9.2 Acceptance Criterion:
9.2.1 Grades R60802 and R60804—All coupons thus tested shall exhibit a continuous, black, lustrous oxide film and be free
of white or brown corrosion product in excess of standards previously agreed upon between manufacturer and purchaser. Coupons
2 2
shall exhibit a weight gain orof not more than 22 mg/dm in a 72-h test or 38 mg/dm in a 336-h test.
9.2.2 Grade R60901—All coupons shall exhibit a continuous, uniform, dark gray oxide film. Coupons shall exhibit a weight
2 2
gain of not more than 35 mg/dm in a 72-h test or 60 mg/dm in a 336-h test.
10. Permissible Variations in Dimensions
10.1 Sheet, strip, or plate shall conform to the permissible variations in dimensions prescribed in the applicable Tables 4-12,
incl.
11. Significance of Numerical Limits
11.1 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.
