(Specification)Standard Specification for Structural Carbon Steel Plates
Standard Specification for Structural Carbon Steel Plates
ABSTRACT
This specification covers structural quality carbon-manganese-silicon steel plates in three tensile strength ranges intended primarily for service at atmospheric temperatures where improved notch toughness is important. If the steel is to be welded, a welding procedure suitable for the grade of steel and intended use or service shall be utilized. The steel shall be made by fine grain practice. Heat and product analysis shall conform to the chemical composition requirements prescribed for carbon, manganese, phosphorus, sulfur, and silicon. The tension test specimen shall conform to the tensile requirements including tensile strength, yield point, and elongation.
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 improved 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 Specification 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 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.

Overview
ASTM A573/A573M-20 is a standard specification developed by ASTM International for structural quality carbon-manganese-silicon steel plates. This standard defines requirements for plates produced in three distinct tensile strength ranges and is particularly intended for applications at atmospheric temperatures where enhanced notch toughness is necessary. The specification outlines criteria for chemical composition, mechanical properties, and applicable supplementary requirements, ensuring reliable performance, especially in structural and welded construction scenarios.
Key Topics
- Scope: Covers carbon-manganese-silicon steel plates intended for structural use in three tensile strength grades, suitable for service at ambient temperatures requiring improved toughness.
- Thickness Limitation: Plates are restricted to a maximum thickness of 1.5 inches (40 mm).
- Weldability: If welding is required, appropriate procedures per ASTM guidelines must be used to match the intended application and plate grade, referencing Specification A6/A6M for details.
- Chemical Composition: Prescribes maximum and minimum content for key elements such as carbon, manganese, phosphorus, sulfur, silicon, and, for wider plates, a minimum aluminum content.
- Mechanical Properties: Specifies required ranges for tensile strength, yield point, and elongation, as demonstrated by tension tests on sample coupons.
- Heat and Product Analysis: Chemical composition is verified by heat analysis and supplemented by product analysis, with tolerance thresholds as per Specification A6/A6M.
- Supplementary Requirements: Allows for additional tests, including the Charpy V-Notch Impact Test, if requested by the purchaser to verify notch toughness for critical service applications.
- Dual Units: Provides requirements in both inch-pound and SI units, which must be used independently to ensure compliance.
Applications
The primary use for ASTM A573/A573M-20 steel plates is in the fabrication of structures where toughness and resistance to impact at normal temperatures are significant factors:
- Storage Tanks: Originally developed for storage tanks operating at ambient conditions, especially where improved fracture resistance is essential.
- Bridges and Buildings: Suitable for critical load-bearing elements in bridges or building frames due to their combination of strength and toughness.
- Welded Construction: Preferred for welded assemblies thanks to controlled weldability criteria and predictable mechanical properties.
- Rolling Stock and Ships: Utilized in rail and marine applications that demand both durability and safety, particularly where sub-zero notch toughness may be considered in design.
- General Structural Steel Applications: Appropriate where enhanced toughness over conventional semi-killed ingot cast steels is needed.
Related Standards
- ASTM A6/A6M: Specification for General Requirements for Rolled Structural Steel Bars, Plates, Shapes, and Sheet Piling; provides detailed general delivery and testing requirements referenced throughout ASTM A573/A573M-20.
- Welding Codes: Proper application may require adherence to relevant welding standards and procedures for structural steel to ensure safety and structural integrity.
- Other ASTM Plate Specifications: Depending on application, other carbon steel plate standards such as ASTM A572 or ASTM A36 may also be considered for comparison or selection.

ASTM A573/A573M-20 is a technical specification published by ASTM International. Its full title is "Standard Specification for Structural Carbon Steel Plates". This standard covers: ABSTRACT This specification covers structural quality carbon-manganese-silicon steel plates in three tensile strength ranges intended primarily for service at atmospheric temperatures where improved notch toughness is important. If the steel is to be welded, a welding procedure suitable for the grade of steel and intended use or service shall be utilized. The steel shall be made by fine grain practice.
