Weathering steel plate ASTM A588 grade A steel properties

Weathering steel plate ASTM A588 grade A steel is a high strength low-alloy structural steel that is used in numerous applications such as bridges, buildings, structures, transmission poles, train tracks, and many more. This steel is known for its superior corrosion resistance properties and is popularly referred to as Corten steel.

Weathering steel is a type of steel alloy that has a significantly higher resistance to atmospheric corrosion compared to other steels. The corrosion resistance of this steel is achieved by the formation of a protective oxide layer on the surface of the steel. This oxide layer is formed due to the presence of chromium, copper, and other alloying elements in the steel.

ASTM A588 grade A steel is one of the most commonly used weathering steel grades. This steel grade is typically used for welded, bolted, and riveted structures. The ASTM A588 grade A steel plate is also known as Corten A steel plate. The steel plate is available in various thicknesses and dimensions.
