STANDARD SPECIFICATION FOR
HIGH-YIELD-STRENGTH, QUENCHED AND TEMPERED ALLOY STEEL
PLATE, SUITABLE FOR WELDING1
This standard is issued under the fixed designation A514/A514M; 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 (ε) 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 quenched and tempered alloy steel plates of structural quality in thicknesses of 6 in. [150 mm] and under intended primarily for use in welded structures and other non-welded structures.
1.2 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 Specification A6/A6M for information on weldability.
1.3 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 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 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.
1 This specification is under the jurisdiction of ASTM Committee A01 on Steel, Stainless Steel and Related Alloys and is the direct responsibility of Subcommittee A01.02 on Structural Steel for Bridges, Buildings, Rolling Stock and Ships.
Current edition approved Sept. 1, 2022. Published September 2022. Originally approved in 1964. Last previous edition approved in 2018 as A514/A514M – 183.

2.1 ASTM Standards:2
3. General Requirements for Delivery
3.1 Plates furnished under this specification shall conform to the applicable requirements of the current edition of Specification A6/A6M unless a conflict exists in which case this specification shall prevail.
4. Materials and Manufacture
4.1 The steel shall be killed and conform to the requirements for fine austenitic grain size in Specification A6/A6M.
5. Heat Treatment
5.1 Except as allowed by 5.2, plates shall be heat treated to conform to the tensile and hardness requirements given in Table 2 by heating to not less than 1650 °F [900 °C], quenching in water or oil, and tempering at not less than 1150 °F [620 °C]. The heat-treatment temperatures shall be reported in the test report.
5.2 Plates ordered without the heat treatment specified in 5.1 shall be stress relieved by the manufacturer, and subsequent heat treatment of the plates to conform to 5.1 shall be the responsibility of the purchaser.
6. Chemical Composition
6.1 The heat analysis shall conform to the requirements given in Table 1.
6.2 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.
7. Mechanical Properties
7.1 Tension Test—The plates as represented by the tension test specimens shall conform to the tensile requirements given in Table 2.
7.2 Hardness Test—For plates ⅜ in. [10 mm] and under in thickness, a Brinell hardness test may be used instead of the tension testing each plate, in which case a tension test shall be made from a corner of each of two plates per lot. A lot shall consist of plates from the same heat, thickness, prior condition, and scheduled heat treatment and shall not exceed 15 tons [15 Mg] in weight [mass]. A Brinell hardness test shall be made on each plate not tension tested and the results shall conform to the hardness requirements given in Table 2.
8. Number of Tests
8.1 Except as allowed by 7.2, one tension test shall be taken from a corner of each plate as heat treated.
9. Retest
9.1 Plates that were subjected to Brinell hardness testing and failed to conform to the specified hardness requirements may be subjected, at the manufacturer's option, to tension testing and shall be accepted if the results conform to the tensile requirements given in Table 2.
9.2 The manufacturer may re-heat treat plates that fail to meet the mechanical property requirements of this specification. All mechanical property tests shall be repeated after such heat treatment.
10. Test Specimens
10.1 If possible, all test specimens shall be cut from the plate in its heat-treated condition. If it is necessary to prepare test specimens from separate pieces, such pieces shall be full thickness, and shall be similarly and simultaneously heat treated with the plate. All such separate pieces shall be of such a size that the prepared test specimens are free of any variation in properties due to edge effects.
10.2 If specified in the purchase order, the test pieces shall be subjected to additional thermal treatments intended to simulate thermal treatments that subsequently might be done by the fabricator.
