Designation: A573/A573M −25
Standard Speciﬁcation for
Structural Carbon Steel Plates
1
This standard is issued under the ﬁxed designation A573/A573M; 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.
1. Scope*
1.1 This speciﬁcation covers structural quality carbon-
manganese-silicon steel plates in three tensile strength ranges.
NOTE 1—This speciﬁcation was originally intended primarily for
construction of storage tanks used at ambient temperatures when im-
proved toughness was needed over that available in semi-killed ingot cast
steels.
1.2 Plates covered by this speciﬁcation are limited to a
maximum thickness of 1.5 in. [40 mm].
1.3 If the steel is to be welded, it is presupposed that a
welding procedure suitable for the grade of steel and intended
use or service will be utilized. See Appendix X3 of Speciﬁca-
tion A6/A6M for information on weldability.
1.4 The values stated in either inch-pound units or SI units
are to be regarded separately as standard. Within the text, the
SI units are shown in brackets. The values stated in each
system are not necessarily exact equivalents; therefore, to
ensure conformance with the standard, each system shall be
used independently of the other, and values from the two
systems shall not be combined.
1.5 This international standard was developed in accor-
dance with internationally recognized principles on standard-
ization established in the Decision on Principles for the
Development of International Standards, Guides and Recom-
mendations issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee.

3. General Requirements for Delivery
3.1 Plates furnished under this speciﬁcation shall conform
to the requirements of the current edition of Speciﬁcation
A6/A6M, unless a conﬂict exists in which case this speciﬁca-
tion shall prevail.
4. Chemical Composition
4.1 The heat analysis shall conform to the requirements
given in Table 1.
4.2 If a product analysis is performed, the product analysis
shall conform to the requirements given in Table 1 subject to
the product analysis tolerances in Speciﬁcation A6/A6M.

摘要：

ASTM A573/A573M-25 是国际通用的结构碳素钢板标准规范，主要涵盖碳锰硅钢热轧厚板的化学成分、力学性能、尺寸偏差及验收要求，适用于桥梁、建筑、储罐及一般工程结构用焊接或铆接构件。该标准包含 A573 Gr.58、Gr.65、Gr.70 三个常用强度等级，分别对应最小抗拉强度 400 MPa、450 MPa 和 485 MPa，并规定了冲击韧性、弯曲成形及超声波检测等可选附加要求。相比普通碳素结构钢标准，A573 强调在保证焊接性能的同时提供更均匀的强度与低温韧性，尤其适合对缺口韧性
