A572

A572 is a type of steel specification defined by the American Society for Testing and Materials (ASTM). It is commonly used in construction and structural applications due to its high strength and durability. The specification covers several grades, each with different minimum yield strengths, often ranging from 42,000 to 65,000 pounds per square inch. A572 steel is known for its excellent weldability and is often used in bridges, buildings, and other structures where strength and resistance to environmental conditions are critical. Its versatility makes it a popular choice in engineering and construction projects.
