ASTM A588 is a specification for high-strength low-alloy structural steel shapes, plates, and bars. It covers material that has atmospheric corrosion resistance, making it suitable for use in structural applications such as bridges, buildings, and other structures.
The specification is applicable to plates up to 4 inches thick, shapes, and bars. The atmospheric corrosion resistance of this steel is achieved through the formation of a protective oxide film on its surface.
ASTM A588 covers the following material grades: A588 Grade A, A588 Grade B, A588 Grade C, and A588 Grade K. Each grade has a unique chemical composition and mechanical properties, but they all provide the desired atmospheric corrosion resistance. The steel shall be made by fine grain practice, normal furnishing in the as-rolled condition, and normalizing rolling. The steel plates, shapes, and bars shall undergo tension test to determine their tensile strength, yield strength, and elongation properties.
In summary, ASTM A588 is a specification that covers high-strength low-alloy structural steel shapes, plates, and bars with atmospheric corrosion resistance. It is used in various applications such as bridges, buildings, and other structures.
