1. High Yield Strength for Demanding Structures
ASTM A913 W Beams are designed for structural applications requiring higher strength levels than conventional structural steel grades. With yield strengths from 50 ksi to 70 ksi, they provide engineers with additional material options when designing heavily loaded structural frames.
2. Advanced Quenching and Self-Tempering Process
The QST manufacturing process uses controlled in-line cooling and self-tempering after hot rolling. This process develops the required mechanical properties in the finished steel section without conventional reheating and quenching after rolling.
3. Suitable for Heavy Structural Applications
ASTM A913 wide flange beams are used in projects where structural strength and reliable material performance are essential, including high-rise buildings, industrial plants, large commercial facilities, and infrastructure structures.
4. Suitable for Welding and Structural Connections
ASTM A913 structural shapes can be used in welded, bolted, or riveted construction. Welding procedures must be selected according to the steel grade, section thickness, fabrication conditions, and applicable engineering requirements.
For structural steel procurement, material traceability and specification compliance are essential.
Each order should be checked against the agreed purchase requirements. Inspection and documentation can include:
Chemical composition analysis
Tensile strength and yield strength testing
Elongation testing
Charpy V-notch impact testing when specified or required
Section dimensions and weight verification
Surface and visual inspection
Heat number identification and material traceability
Mill Test Certificate (MTC)
Inspection requirements, sampling frequency, and certification documents should be confirmed before production or shipment.
High-Rise Buildings: Main columns, structural beams, transfer structures, and heavy-load framing systems.
Industrial Buildings: Factory buildings, manufacturing facilities, power plants, and heavy industrial workshops.
Steel Warehouses: Primary structural frames, long-span roof systems, and load-bearing components.
Infrastructure Projects: Bridges and other structural engineering applications designed for the specified A913 grade.
Commercial Buildings: Large commercial developments, convention centers, and multi-story steel structures.

4. What is the difference between ASTM A913 and ASTM A992 W Beam?
Both are used for structural wide flange sections. A992 has a minimum yield strength of 50 ksi, while A913 offers multiple higher-strength grades, including 60, 65, and 70 ksi. A913 is produced using the QST process.
5. What is the QST manufacturing process?
QST stands for Quenching and Self-Tempering. It is an in-line heat treatment process that uses controlled cooling after rolling to achieve the specified mechanical properties.
6. Can ASTM A913 W Beams be welded?
Yes. ASTM A913 shapes are intended for welded, bolted, or riveted construction. However, the welding procedure must be suitable for the material grade, thickness, and intended application.
7. What W Beam sizes can be supplied?
W Beam sizes depend on mill production capabilities and grade availability. Buyers should provide the required section designation, such as W12×50 or W14×90, for confirmation.
8. What documents are available for ASTM A913 W Beam orders?
Material documentation may include a Mill Test Certificate, chemical analysis, mechanical test results, heat number identification, and other inspection records agreed upon in the purchase order.
9. Is ASTM A913 suitable for high-rise buildings?
Yes. Its high-strength grades are suitable for structural applications in high-rise buildings and heavily loaded steel frames, subject to engineering design and project specifications.
