Standard Specification for Wrought Zirconium and Zirconium Alloy Seamless and Welded Tubes for Nuclear Service (Except Nuclear Fuel Cladding)

ABSTRACT
This specification covers the standard requirements for wrought zirconium and zirconium alloy seamless and welded tubes for nuclear applications except for nuclear fuel cladding. Five grades of reactor grade zirconium and zirconium alloys with R60001, R60802, R60804, R60901, and R60904 UNS number designations are described. Material shall be made from ingots produced by vacuum arc melting, electron beam melting, or other melting process to be carried out in furnaces conventionally used for reactive metals. Seamless tubes may be made by billet extrusion with subsequent cold working, by drawing, swaging, or rocking, with intermediate annealing. Welded tubing shall be made from flat-rolled products by an automatic or semiautomatic welding process with no addition of filler metal and shall be cold reduced by drawing, swaging, or rocking. The products shall be in the recrystallized or cold-worked and stress-relieved conditions and shall be furnished by as-cold reducing, pickling, grounding, polishing, or end-saw cutting, machining, or shearing. Chemical and product analysis shall be performed on the materials which shall meet the chemical composition requirements for tin, iron, chromium, nickel, niobium, oxygen, and other impurity elements. The tensile properties shall be determined by a tensile test method and shall conform to the tensile strength, yield strength, and elongation limits. Steam and water corrosion tests and hydrostatic test shall be conducted to determine the acceptance criteria for corrosion and internal hydrostatic pressure, respectively. Burst properties, contractile strain ratio, grain size, and hydride orientation of the finished tubing shall also be determined.
SIGNIFICANCE AND USE

SCOPE
1.1 This specification covers seamless and welded wrought zirconium and zirconium-alloy tubes for nuclear application. Nuclear fuel cladding is covered in Specification B811.  
1.2 Five grades of reactor grade zirconium and zirconium alloys suitable for nuclear application are described.  
1.2.1 The present UNS numbers designated for the five grades are given in Table 1.  
1.3 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.  
1.4  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.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

The strength of zirconium alloys is a function of their metallurgical condition, alloy content, and impurity level, especially oxygen. The strength values listed above are
for alloys that contain oxygen concentrations in the range 900 to 1400 ppm. For alloys with other oxygen concentrations, the tensile properties are to be agreed upon
between the manufacturer and the purchaser.
B
To be agreed upon between the manufacturer and the purchaser.
C
The tensile test is to be carried out at one or more of the temperatures listed in Table 3 (or at another temperature) as agreed upon between the manufacturer and
purchaser. If one of the above temperatures is selected, the minimum properties shall be as listed for that temperature. If a different temperature is selected, the minimum
properties shall be agreed upon between the manufacturer and purchaser.
D
Paragraph 6.9.1 in Test Methods E8 allows small diameter tubes to be tested as full size tubular sections with snug-fitting metal plugs inserted into the ends of the tube
to permit proper gripping by the test machine jaws, as shown in Fig. 11 in Test Methods E8. Specimens for the testing of large diameter tubes are cut from the wall of the
tube and are to satisfy the requirements of Figs. 12 and 13 in Test Methods E8.
E
The properties in this table apply to tubes 0.125 in. (3.2 mm) outside diameter and larger, and 0.015 in. (0.38 mm) wall and thicker. Mechanical properties of tubes outside
these limits are to be agreed upon between the manufacturer and purchaser.
F
“RT” represents room temperature; Note 4 in Test Methods E8 and 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.

A
The strength of zirconium alloys is a function of their metallurgical condition, alloy content, and impurity level, especially oxygen. The strength values listed above are
for alloys that contain oxygen concentrations in the range 900 to 1400 ppm. For alloys with other oxygen concentrations, the tensile properties are to be agreed upon
between the manufacturer and the purchaser.
B
To be agreed upon between the manufacturer and the purchaser.
C
The tensile test is to be carried out at one or more of the temperatures listed in Table 3 (or at another temperature) as agreed upon between the manufacturer and
purchaser. If one of the above temperatures is selected, the minimum properties shall be as listed for that temperature. If a different temperature is selected, the minimum
properties shall be agreed upon between the manufacturer and purchaser.
D
Paragraph 6.9.1 in Test Methods E8 allows small diameter tubes to be tested as full size tubular sections with snug-fitting metal plugs inserted into the ends of the tube
to permit proper gripping by the test machine jaws, as shown in Fig. 11 in Test Methods E8. Specimens for the testing of large diameter tubes are cut from the wall of the
tube and are to satisfy the requirements of Figs. 12 and 13 in Test Methods E8.
E
The properties in this table apply to tubes 0.125 in. (3.2 mm) outside diameter and larger, and 0.015 in. (0.38 mm) wall and thicker. Mechanical properties of tubes outside
these limits are to be agreed upon between the manufacturer and purchaser.
F
“RT” represents room temperature; Note 4 in Test Methods E8 and 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 Material covered by this specification shall be made from ingots produced by multiple vacuum arc melting, 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.
5.2 The tubes shall be made by a process approved by the purchaser.
5.3 Seamless tubes may be made by any method that will yield a seamless product that meets the requirements of this
specification. One such method is extrusion of billets with subsequent cold working, by drawing, swaging, or rocking, with
intermediate anneals until the final dimensions are reached.
5.4 Unless otherwise agreed upon between the manufacturer and purchaser, welded tubing shall be made from flat-rolled
products by an automatic or semiautomatic welding process with no addition of filler metal in the welding operation. Other
methods of welding, such as the addition of filler metal or hand welding, may be employed if approved by the purchaser and tested
by methods agreed upon between the manufacturer and the purchaser. If filler wire is used, it must meet the chemical requirements
of the appropriate grade as shown in Table 4. Welded tube is normally cold reduced to the desired dimensions by such methods
as drawing, swaging, or rocking. The manufacturer must prevent contamination during welding by use of proper precautions.
