Frequently Asked Questions

Learn more about A656 steel plate.
A656 is typically a better fit when a project needs HSLA steel plate with improved formability for fabricated parts such as crane booms, truck frames, rail cars, construction equipment and transportation components. A572 is also an HSLA structural steel, but A656 is more closely associated with applications where strength-to-weight performance and formability are especially important. Ultimately the appropriate grade depends on the project's engineering requirements, fabrication needs and specifications.
A656 steel plate is commonly used in fabricated structural applications that require strength, formability and toughness. Common uses include construction equipment, crane booms, rail cars, heavy vehicle frames and general fabrication. Because A656 is suitable for ambient and low-temperature applications, it can support fabricated components used across a wider range of environments.
“As-rolled condition” means the plate is supplied after the rolling process without additional heat treatment unless otherwise specified. For A656, this matters because the grade is designed to offer improved formability, weldability and notch toughness in that supplied condition.
