Corten steel is also known as weathering steel. This type of steel is available in various grades, including ASTM A588 grade A, ASTM A588 grade B, ASTM A588 grade C, ASTM A588 grade K.
The ASTM A588 grade A plates have intermediate-level of atmospheric corrosion resistance and are highly corrosion resistant to prolonged contact with moisture. This is due to the addition of alloying elements such as copper, chromium and nickel. The ASTM A588 grade B plates have high-level of atmospheric corrosion resistance. The presence of magnesium and phosphorus in the alloy increases the strength of the steel and gives it excellent tensile strength and hardness.
Corten steel A588 grade plates materials exhibit superior corrosion resistance over regular carbon steel as a result of the development of a protective oxide film on the surface that provides a 5182-Y protection performance. The atmospheric corrosion resistance of A588 grade A is substantially better than that of carbon steels such as A572 grade 50 and A529 grade 50 in most environmental conditions. In addition, this type of steel exhibits higher strength than typically found in steel with improved atmospheric corrosion resistance.
The ASTM A588 grade A plates offer various thicknesses. The thickness of the Corten steel A588 grade plates materials range from 3mm up to 12mm. Due to the process of rolling and forming, the Corten steels may have slightly different thicknesses along their length. The surface finish of these plates can either be hot rolled, annealed or pickled.
The ASTM A588 grade B plates are used in applications where corrosion resistance is the primary concern. This type of steel is available in several different grades, ranging from heavily alloyed to simple form steel grades. Generally, the A588 grade B plates are used for high-strength low-alloy structural applications that require welding. The corrosion-resistance of the A588 grade B plates makes them a great option for applications that are constantly exposed to moisture. These plates are widely used in bridge and other structures where the atmosphere is highly corrosive.
The ASTM A588 grade C plates are designed for applications that require moderate strength and good corrosion resistance. The A588 grade C typically has higher levels of copper and chromium, which both impart extra corrosion resistance to the steel. These plates can easily withstand corrosive environments, making them suitable for applications like shipbuilding, bridges, and other outdoor applications.
The ASTM A588 grade K plates are considered highly wear-resistant due to their high tensile strength and hardness. The combination of chromium and nickel additionally increases the wear-resistance of the steel, making the A588 grade K plates ideal for applications that require a combination of strength and durability. These plates are popular in industrial and commercial settings, especially those where abrasive materials are in contact with them.
Overall, the Corten steel A588 grade plates materials offer excellent corrosion resistance while providing structural strength and toughness. The steel plates provide a balance between weathering and corrosion, making them highly durable in outdoor and wet applications.
