Standard Specification for Nickel-Copper Alloy (UNS N04400)* Seamless Pipe and Tube

SCOPE
1.1 This specification covers nickel-copper alloy UNS N04400* in the form of cold-worked seamless pipe and tube in the conditions shown in Table 1 and Table X1.1.
1.1.1 Hot worked material is available. Properties and permissible tolerances are to be agreed upon between the manufacturer and purchaser.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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 become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations prior to use.

They apply to cut lengths up to and including 24 ft (7.3 m). For lengths over 24 ft,
an additional over-tolerance of ⁄8 in. (3.2 mm) for each 10 ft (3.0 m) or fraction
thereof shall be permissible up to a maximum additional over-tolerance of ⁄2 in.
(12.7 mm).
8. Workmanship, Finish and Appearance
8.1 The material shall be uniform in quality and temper, smooth, commercially straight, and free of injurious imperfections.
9. Sampling
9.1 Lot Definition:
9.1.1 A lot for chemical analysis shall consist of one heat.
9.1.2 Alot for all other testing shall consist of all material from the same heat, nominal size (excepting length), and condition.
9.1.2.1 Where material cannot be identified by heat, a lot shall consist of not more than 500 lb (227 kg) of material in the same
condition and nominal size (excepting length).
9.2 Test Material Selection:
9.2.1 Chemical Analysis—Representative samples from each lot shall be taken during pouring or subsequent processing.
9.2.1.1 Product (Check) Analysis shall be wholly the responsibility of the purchaser.
9.2.2 Mechanical and other Properties —Samples of the material to provide test specimens for mechanical and other properties
shall be taken from such locations in each lot as to be representative of that lot. Test specimens shall be taken from material in
the final condition.
10. Number of Tests
10.1 Chemical Analysis—One test per lot.
10.2 Tension—One test per lot.
10.3 Hydrostatic— Each piece in each lot.
11. Specimen Preparation:
11.1 Room Temperature Tensile Specimen —Material shall be tested in the direction of fabrication. Whenever possible, all pipe
and tube shall be tested in full tubular size. When testing in full tubular size is not possible, longitudinal strip specimens, or the
largest possible round specimen, shall be used. In the event of disagreement when full tubular testing is not possible, a longitudinal
strip specimen with reduced gauge length as contained in Test Methods E 8E 8 shall be used.
12. Test Methods
12.1 Chemical Composition—In case of disagreement, the chemical composition shall be determined in accordance with Test
Methods E 76E 76.
12.2 Tension Test— Tension testing shall be conducted in accordance with Test Methods E 8E 8.

12.3 Hydrostatic Test— Each pipe or tube with an outside diameter ⁄8 in. (3 mm) and larger and with wall thickness of 0.015
in. (0.38 mm) and over shall be tested by the manufacturer to an internal hydrostatic pressure of 1000 psi (6.9 MPa) provided that
the fiber stress calculated in accordance with the following equation does not exceed the allowable fiber stress, S, indicated below:
P 5 2St/D
where:
P = hydrostatic test pressure, psi (or MPa)
S = allowable fiber stress, for material in the condition (temper) furnished as follows:
Annealed:
5 in. (127 mm) outside diameter 17 500 psi
and under (120 MPa)
Over 5 in. (127 mm) outside diameter 16 700 psi
(115 MPa)
Stress-relieved:
All sizes 21 200 psi
(145 MPa)
t = minimum wall thickness, in. (or mm), equal to the specified nominal wall minus the permissible minus wall tolerance, or
the specified minimum wall thickness, and,
D = outside diameter of the pipe or tube, in. (or mm).
12.3.1 When so agreed upon between the manufacturer and purchaser, pipe or tube may be tested to 1 ⁄2 times the allowable
fiber stress given above.
12.4 Rounding Method—For purposes 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 below, in accordance with the
rounding method of Practice E 29E 29:
Rounded Unit for Observed
Test
or Calculated Value
Chemical composition and toler- nearest unit in the last right-hand place of fig-
ances (when expressed in deci- ures of the specified limit. If two choices are
mals) possible, as when the digits dropped are ex-
actlya5ora5followed only by zeros,
choose the one ending in an even digit with
zero defined as an even digit.
Tensile strength, yield strength nearest 1000 psi (6.9 MPa)
Elongation nearest 1 %
13. Inspection
13.1 Inspection of the material shall be agreed upon between the purchaser and the supplier as part of the purchase contract.
14. Rejection and Rehearing
14.1 Material that fails to conform to the requirements of this specification may be rejected. Rejection should be reported to the
producer or supplier promptly and in writing. In case of dissatisfaction with the results of the test, the producer or supplier may
make claim for a rehearing.
15. Certification
15.1 When specified in the purchase order or contract, a manufacturer’s certification shall be furnished to the purchaser stating
that material has been manufactured, tested, and inspected in accordance with this specification, and that the test results on
representativesamplesmeetspecificationrequirements.Whenspecifiedinthepurchaseorderorcontract,areportofthetestresults
shall be furnished.
16. Product Marking
16.1 Thefollowinginformationshallbemarkedonthematerialorincludedonthepackage,oronalabelortagattachedthereto:
The name of the material or UNS number, heat number, condition (temper), this specification number, the size, gross, tare and net
weight, consignor and consignee address, contract or order number, or such other information as may be defined in the contract
