ASTM A514 is a high-strength, low-alloy structural steel plate available in several grades, including A514 Grade B, E, F, H, P, and Q. It is heat-treated to provide high yield and tensile strength while maintaining good toughness and weldability. A514 steel is commonly used in heavy-duty structures, cranes, bridges, construction equipment, pressure applications, and other demanding applications where reduced plate thickness and high structural strength are required.
Final chemical, mechanical properties, dimensions and tolerances are confirmed against the governing specification and purchase order.
