While material in the T42 and T62 tempers is not available from the material producer, the properties are listed to indicate those which can usually be obtained by the
userwhenthematerialisproperlysolutionheattreatedorsolutionandprecipitationheattreatedfromtheO(annealed)orF(as-fabricated)tempers.Thesepropertiesapply
when samples of material supplied in the O or F temper are heat treated by the producer to the T42 or T62 tempers to determine that the material will respond to proper
thermal treatment. Properties attained by the user, however, may be lower than those listed if the material has been formed or otherwise cold or hot worked, particularly
in the annealed temper, prior to solution heat treatment.

Material in the T42 and T62 tempers is not available from the material producers.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: B241/B241M − 16 B241/B241M − 22 Used in USNRC-RDT standards
Standard Specification for
Aluminum and Aluminum-Alloy Seamless Pipe and
Seamless Extruded Tube
This standard is issued under the fixed designation B241/B241M; the number immediately following the designation indicates the year
of original 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 (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope*
1.1 This specification covers aluminum and aluminum–alloy seamless pipe in the alloys (Note 1) and tempers shown in Table
1 [Table 2] and and seamless extruded round tube in the alloys and tempers shown in Table 31 [Table 4]2] intended for pressure
applications. The standard sizes for seamless pipe are listed in Table 16.7 of ANSI H35.2 and H35.2(M). Nonstandard alloys,
tempers, and sizes of pipe are produced as seamless extruded tube. Also included in this standard are seamless extruded pipe and
seamless extruded tube for Oil & Gas Transmission previously covered under Specification B345/B345M.
NOTE 1—Throughout this specification, use of the term alloy, in the general sense, includes aluminum as well as aluminum alloy.
NOTE 2—For drawn seamless tubes, see SpecificationsSpecification B210B210/B210M and B210M; for extruded tubes, Specifications B221 and B221M;
for drawn seamless tubes for condensers and heat exchangers, Specifications B234 and B234M; for seamless condenser and heat exchanger tubes with
integral fins, Specification B429/B429M; and for drawn tube for general purpose applications, SpecificationsSpecification B483/B483M.
1.2 Alloy and temper designations are in accordance with ANSI H35.1/H35.1(M). The equivalent Unified Numbering System
alloy designations are those of Table 5Table 4 preceded by A9, for example, A91100 for aluminum 1100 in accordance with
Practice E527.
1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the
two systems may result in non-conformance with the standard.
1.4.1 The SI units are shown either in brackets or in separate tables.
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.
This specification is under the jurisdiction of ASTM Committee B07 on Light Metals and Alloys and is the direct responsibility of Subcommittee B07.03 on Aluminum
Alloy Wrought Products.

A
The basis for establishment of mechanical property limits is shown in Annex A1.
B
To determine conformance to this specification, each value for ultimate strength and for yield strength shall be rounded to the nearest 0.1 ksi and each value for elongation
to the nearest 0.5 %, both in accordance with the rounding-off-method of Practice E29.
C
Elongation of full-section and cut-out sheet-type specimens is measured in 2 in.; offor round specimens, in 4 × specimen diameter. See 9.1.1 for conditions under which
measurements are not required.
D
Tests for tensile properties in the F temper are not required.No mechanical properties are specified, guaranteed, or provided.
E
For stress relieved tempers (T3510, T3511, T4510, T4511, T5510, T5511, T6510, T6511, T73510, T73511, T8510, T8511), characteristics and properties other than those
specified may differ somewhat from the corresponding characteristics and properties of material in the basic tempers.
F
While material in the T42 and T62 tempers is not available from the material producer, the properties are listed to indicate those which can usually be obtained by the
user when the material is properly solution heat treated or solution and precipitation heat treated from the O (annealed) or F (as-fabricated) tempers. These properties apply
when samples of material supplied in the O or F temper are heat treated by the producer to the T42 or T62 tempers to determine that the material will respond to proper
thermal treatment. Properties attained by the user, however, may be lower than those listed if the material has been formed or otherwise cold or hot worked, particularly
in the annealed temper, prior to solution heat treatment.
G
Material in the T42 and T62 tempers is not available from the material producers.
H
Formerly designated T42 temper. When properly aged (precipitation heat-treated) 6063-T1 extruded products are designated T5.
6.2.1 For heat-treated tempers, an inspection lot shall consist of an identifiable quantity of material of the same mill form, alloy,
temper, and nominal dimensions traceable to a heat-treat lot or lots, and subjected to inspection at one time.
6.2.2 For non-heat treated tempers, an inspection lot shall consist of an identifiable quantity of material of the same mill form
alloy, temper, and nominal dimensions subjected to inspection at one time.
7. Composition
7.1 Limits—The pipe or tube shall conform to the composition limits specified in Table 5.4. Conformance shall be determined by
the producer, by taking samples in accordance with Practices E716, when the ingots are poured, and analyzing those samples in
accordance with Test Methods E34E1251, E607E3061, E1251, or EN 14242. At least one sample shall be taken for each group
of ingots poured simultaneously from the same source of molten metal. If the producer has determined the composition during
pouring of the ingots, they shall not be required to sample and analyze the finished product.
7.2 If it becomes necessary tooto analyze the finished or semi-finished product for conformance to chemical composition limits,
the methods of sampling and methods of analysis shall be as provided in the following:
7.2.1 Methods of Sampling—Samples for chemical analysis shall be taken in accordance with Practice B985.
7.2.2 Methods of Analysis—Analysis shall be performed in accordance with Test Methods E607, E1251, E34E3061, or CEN EN
14242 (ICP method).
NOTE 4—It is standard practice in the United States aluminum industry to determine conformance to the composition limits prior to further processing
of ingots into wrought products. Due to the continuous nature of the process, it is not practical to keep a specific ingot analysis identified with a specific
quantity of finished material.

The basis for establishment of tensile property limits is shown in Annex A1.
B
To determine conformance to this specification, each value for tensile strength and yield strength shall be rounded to the nearest 1 MPa and each value for elongation
to the nearest 0.5 %, both in accordance with the rounding-off method of Practice E29.
C
Elongation in 50 mm apply for shapes tested in full section and for sheet-type specimens machined from material up through 12.5 mm in thickness having parallel
surfaces. Elongations in 5 D,D (5.65 A), where D and A are diameter and cross-sectional area of the specimen respectively, apply to round test specimens machined
œ
from thicknesses over 6.30. See 9.1.1 for conditions under which measurements are not required.
D
No mechanical properties are specified specified, guaranteed, or guaranteed.provided.
E
For stress-relieved tempers (T3510, T3511, T4510, T4511, T5510, T5511, T6510, T6511, T73510, T73511, T76510, T76511, T8510, T8511), characteristics and
properties offerother than those specified may differ somewhat from the corresponding characteristics and properties of material in the basic tempers.
F
While material in the T42 and T62 tempers is not available from the material producer, the properties are listed to indicate those which can usually be obtained by the
user when the material is properly solution heat treated or solution and precipitation heat treated from the O (annealed) or F (as-fabricated) tempers. These properties apply
when samples of material supplied in the O or F temper are heat treated by the producer to the T42 or T62 tempers to determine that the material will respond to proper
thermal treatment. Properties attained by the user, however, may be lower than those listed if the material has been formed or otherwise cold or hot worked, particularly
in the annealed temper, prior to solution heat treatment.
G
Material in the T42 and T62 tempers is not available from the material producers.
H
For Table 12.1 in both ASD and ASD(M):
For purposes of harmonization, the 5D and 50 mm elongation limits were established to match extruded tube elongation values previously published in EN 755-2 [1997].
The relationship among the US customary and metric elongation values does not comply with the conversion rules of the Aluminum Association.

NOTE 5—It is difficult to obtain a reliable analysis of each of the components of clad materials using material in its finished state. A reasonably accurate
determination of the core composition can be made if the cladding is substantially removed prior to analysis. The cladding composition is more difficult
to determine because of the relatively thin layer and because of diffusion of core elements to the cladding. The correctness of cladding alloy used can
usually be verified by a combination of metallographic examination and spectrochemical analysis of the surface at several widely separated points.
