ASTM A830/A830M-24

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: A830/A830M − 18 A830/A830M − 24
Standard Specification for
Plates, Carbon Steel, Structural Quality, Furnished to
Chemical Composition Requirements
This standard is issued under the fixed designation A830/A830M; 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 steel plates furnished to chemical composition requirements.
1.2 The plates are available in several standard steel grades and non-standard grades.
1.3 The plates are usually furnished in the as-rolled (hot-rolled) condition.
1.4 Supplementary requirements are provided for additional requirements that may be specified on the order.
1.5 When 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 Specification A6/A6M for information on weldability.
1.6 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.
1.7 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.

3.1.2 Limitation on rimmed or capped steel.
3.1.3 An alternate designation (CS or DS, see Supplementary Requirement S98) may be used.
4. Materials and Manufacture
4.1 The steel shall be killed.
5. Chemical Composition
5.1 The heat analysis shall conform to the requirements for the applicable grade listed in Table 1, unless otherwise specified as
permitted in 5.2.
5.2 The chemical requirements for heat analysis may be specified in accordance with the ranges and limits listed in Table 2. In
such instances, the heat analysis shall conform to the requirements specified on the order.
5.3 When silicon is required, the range on heat analysis shall be from 0.150.15 % to 0.40 % unless otherwise specified on the order
(see Supplementary Requirement S96).
5.4 When a purchaser specifies a product analysis in accordance with Supplementary Requirement S2, the product analysis shall
conform to the requirements given in Table 1, subject to the product analysis tolerances in Specification A6/A6M.
6. General Requirements
6.1 Material furnished under this specification shall conform to the requirements of the current edition of Specification A6/A6M,
for the ordered material, unless a conflict exists in which case this specification shall prevail.
