ASTM A572/A572M-02

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.

Steel
This standard is issued under the fixed designationA572/A572M; 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 (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
1. Scope
1.1 This specification covers five grades of high-strength low-alloy structural steel shapes, plates, sheet piling, and bars. Grades
42 [290], 50 [345], and 55 [380] are intended for riveted, bolted, or welded structures. Grades 60 [415] and 65 [450] are intended
for riveted or bolted construction of bridges, or for riveted, bolted, or welded construction in other applications.
1.2 For applications, such as welded bridge construction, where notch toughness is important, notch toughness requirements are
to be negotiated between the purchaser and the producer.
1.3 The use of columbium, vanadium, titanium, nitrogen, or combinations thereof, within the limitations noted in Section 5, is
required; the selection of type (1, 2, 3, 4, or 5) is at the option of the producer, unless otherwise specified by the purchaser. (See
Supplementary Requirement S90.)
1.4 The maximum thicknesses available in the grades and products covered by this specification are shown in Table 1.
1.5 When the steel is to be welded, a welding procedure suitable for the grade of steel and intended use or service is to be
utilized. See Appendix X3 of Specification A 6/A 6M for information on weldability.
1.6 Thevaluesstatedineitherinch-poundunitsorSIunitsaretoberegardedseparatelyasstandard.Withinthetext,theSIunits
are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system is to be used
independently of the other, without combining values in any way.
1.7 The text of this specification contains notes or footnotes, or both, that provide explanatory material. Such notes and
footnotes, excluding those in tables and figures, do not contain any mandatory requirements.
1.8 For structural products cut from coiled product, the additional requirements, including additional testing requirements and
the reporting of additional tests, of A 6/A 6M apply.

3. General Requirements for Delivery
3.1 Material furnished under this specification shall conform to the applicable requirements of the current edition of
Specification A 6/A 6M, for the ordered material, unless a conflict exists in which case this specification shall prevail.
3.1.1 Coiled product is excluded from qualification to this specification until leveled and cut to length. Structural products
produced from coil means structural products that have been cut to individual lengths from a coiled product and are furnished
without heat treatment. The processor decoils, levels, cuts to length, and marks the product. The processor is responsible for
performing and certifying all tests, examinations, repairs, inspections, or operations not intended to affect the properties of the
material. For structural products produced from coils, two test results shall be reported for each qualifying coil (Note 1).
NOTE 1—Additional requirements regarding structural products from coil are described in A 6/A 6M.
