ASTM B632/B632M-18

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: B632/B632M − 15 B632/B632M − 18
Standard Specification for
Aluminum-Alloy Rolled Tread Plate
This standard is issued under the fixed designation B632/B632M; 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-alloy rolled flat tread plate, mill-finish, with a raised pattern on one side, in the alloy,
tempers, and thicknesses shown in Table 1 and Table 2 [Table 3].
1.2 Alloy and temper designation are in accordance with ANSI H35.1/H35.1M. The equivalent Unified Numbering System
alloy designation are those of Table 1 preceded by A9, which is A96061 for alloy 6061 and A93003 for Alloy 3003 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 inch-pound or SI units are to be regarded separately as standard. The SI units are shown either
in brackets or in separate tables. The values stated in each system are not exact equivalents; therefore, each system must be used
independently of the other. Combining values from the two systems will result in nonconformance with the specification.
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.

3. Terminology
3.1 Definitions: Refer to Terminology B881 for definitions of product terms used in this specification.
3.2 Definitions of Terms Specific to This Standard:
3.2.1 capable of—The term capable of as used in this specification means that the tests need not be performed. However, should
testing by the purchaser establish that the material does not meet these requirements, the material shall be subject to rejection.
4. Ordering Information
4.1 Orders for material under this specification shall include the following information:
4.1.1 This specification designation (which includes the number, the year, and the revision letter, if applicable),
NOTE 1—For inch-pound orders, specify Specification B632; for metric orders, specify Specification B632M. Do not mix units.

4.1.3 Alloy (7.1),
4.1.4 Temper (9.1),
4.1.5 Dimensions (thickness, width, and length),
4.2 Additionally, orders for material to this specification shall include the following information when required by the
purchaser:
4.2.1 Whether tension test specimens that retain the pattern are unacceptable (Table 2, footnote C).
4.2.2 Whether bend tests are required (10.1),
4.2.3 Whether inspection or witness of inspection and tests by the purchaser’s representative is required prior to material
shipment (13.1),
4.2.4 Whether certification of the material by the producer or supplier is required (17.1),
4.2.5 Whether marking is required (15.1), and
4.2.6 Whether Practices B660 applies and, if so, the levels of preservation, packaging, and packing required (16.3).
5. Responsibility for Quality Assurance
5.1 Responsibility for Inspection and Tests—Unless otherwise specified in the contract or purchase order, the producer is
responsible for the performance of all inspection and test requirements specified herein. The producer may use his own or any other
suitable facilities for the performance of the inspection and test requirements specified herein, unless disapproved by the purchaser
in the order or at the time of contract signing. The purchaser shall have the right to perform any of the inspections and tests set
forth in this specification where such inspections are deemed necessary to assure that material conforms to prescribed requirements.
5.2 Lot Definition—An inspection lot shall be defined as follows:
5.2.1 For heat-treated tempers, an inspection lot shall consist of an identifiable quantity of material of the same mill form, alloy,
temper, and thickness traceable to a heat-treat lot or lots, and subjected to inspection at one time.
5.2.2 For non-heat-treated tempers, an inspection lot shall consist of an identifiable quantity of material of the same mill form,
alloy, temper, and thickness subjected to inspection at one time.
6. General Quality
6.1 Unless otherwise specified, all tread plate shall be supplied in the mill finish and shall be uniform as defined by the
requirements of this specification and shall be commercially sound. Any requirement not so covered is subject to negotiation
between the producer and the purchaser.
6.2 Each piece shall be examined to determine conformance to this specification with respect to general quality and
identification marking. On approval of the purchaser, however, a system of statistical quality control may be used for such
examinations.
7. Chemical Composition
7.1 Limits—The tread plate shall conform to the chemical composition limits specified in Table 1. 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 E34, E607, E1251, or EN14242. 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 chemical composition
during pouring of the ingots, they shall not be required to sample and analyze the finished product.
NOTE 2—It is standard practice in the United States aluminum industry to determine conformance to the chemical 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.
7.2 If it becomes necessary to analyze tread plate 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 E34, E607, E1251, or EN14242.
8. Heat Treatment
8.1 Producer or supplier heat treatment for the applicable tempers of alloy 6061 in Table 2 [Table 3] shall be in accordance with
either Practice B918B918/B918M. or AMS2772.
9. Tensile Properties of Materials as Supplied
9.1 Limits—The tread plate shall conform to the tensile properties specified in Table 2 [Table 3].
9.2 Number of Specimens—One specimen shall be taken from a randomly selected piece representing the following quantities
of tread plate in a lot:
