Standard Specification for Structural Steel Shapes
ABSTRACT
This specification covers rolled steel structural shapes for use in building framing or bridges, or for general structural purposes. Heat analysis shall be used to determine the percentage of carbon, manganese, phosphorus, sulfur, vanadium, titanium, nickel, chromium, molybdenum, columbium, and copper for the required chemical composition. Tension test shall be used to evaluate the required tensile properties such as tensile strength, yield strength and elongation.
SCOPE
1.1 This specification covers rolled steel structural shapes for use in building framing or bridges, or for general structural purposes.
1.2 Supplementary requirements are provided for use where additional testing or additional restrictions are required by the purchaser. Such requirements apply only when specified in the purchase order.
1.3 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 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 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.
1.6 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 A992/A992M-22: Standard Specification for Structural Steel Shapes is a globally recognized standard published by ASTM International. This specification defines the requirements for rolled steel structural shapes, widely used in building framing, bridges, and a variety of general structural applications. ASTM A992 structural steel is known for its high strength, excellent weldability, and reliable performance in diverse construction projects. This standard ensures uniformity in quality and performance characteristics, helping engineers and fabricators meet safety and design expectations in structural steelwork.
Key Topics
- Material Requirements: ASTM A992/A992M-22 specifies the use of killed steel, controlling composition with nitrogen-binding elements or specific nitrogen content.
- Chemical Composition: The standard provides strict limits on elements such as carbon, manganese, vanadium, columbium (niobium), phosphorus, sulfur, copper, nickel, chromium, and molybdenum, enhancing weldability and toughness.
- Mechanical Properties:
- Minimum tensile strength: 65 ksi [450 MPa]
- Yield point: 50 to 65 ksi [345 to 450 MPa]
- Maximum yield-to-tensile ratio: 0.85
- Minimum elongation: 18% in 8 in. [200 mm], 21% in 2 in. [50 mm]
- Supplementary Requirements: Optional testing methods, such as ultrasonic examination, Charpy V-Notch impact testing, and maximum tensile strength limits, may be specified by buyers for additional assurance.
- Unit Consistency: Both inch-pound and SI units are standard, but values from each system must be applied independently per the specification.
- Weldability: The standard requires the use of welding procedures appropriate to A992 steel and provides references for additional information on weldability.
Applications
ASTM A992/A992M-22 is essential for:
- Building Framing: Utilized extensively in wide-flange beams, columns, and other load-bearing steel members due to predictable mechanical properties and superior weldability.
- Bridge Construction: Facilitates robust, durable structural shapes suitable for the demanding loads and environmental factors typical in bridge projects.
- General Structural Uses: Ideal for industrial frames, commercial buildings, and infrastructure due to its consistent quality, making it easier for fabricators and constructors to design safe and efficient structures.
- Welded Construction: ASTM A992 is optimized for jobs requiring reliable welded connections, simplifying the fabrication process and reducing onsite complications.
Related Standards
The ASTM A992/A992M-22 specification references and is commonly used in conjunction with several other structural steel standards:
- ASTM A6/A6M: General requirements for rolled structural steel bars, plates, shapes, and sheet piling.
- ASTM A898/A898M: Specification for straight beam ultrasonic examination of rolled steel shapes, providing nondestructive testing methods for quality control.
- Other Relevant Steel Standards: ASTM A36, ASTM A572, and ASTM A913, which specify different grades and requirements for structural steel, may be selected depending on specific project criteria.
Practical Value
Compliance with ASTM A992/A992M-22 assures that project stakeholders are using high-quality structural steel shapes that meet stringent mechanical and chemical requirements. This helps:
- Optimize structural performance
- Reduce fabrication and construction risks
- Ensure compatibility with modern building codes
- Support sustainability and material efficiency in steel construction
By adhering to this widely adopted standard, engineers, designers, steel manufacturers, and contractors can consistently achieve durable, safe, and cost-effective steel structures in a wide array of construction and civil engineering applications.
