ASTM A588 Grade B is a high strength, low alloy structural steel with improved atmospheric corrosion resistance for structural applications such as bridges, buildings and other structures.
ASTM A588 Grade B is a high strength, low alloy structural steel with improved atmospheric corrosion resistance for structural applications such as bridges, buildings and other structures. It is often specified for structural steel construction projects where its corrosion resistance activities are required or enhanced. The material is available in several shapes including plates, bars, angles, rounds, flats and tubes.
The chemical composition of ASTM A588 Grade B consists of manganese, phosphorus, silicon, sulfur, chromium, copper, and nickel and is normally available in hot-rolled or cold-rolled form. It is well known for its excellent weldability and high yields with relatively low levels of carbon content. It also has good mechanical properties that make it ideal for various structural applications.
ASTM A588 Grade B steel is most often available in standard sizes. These are 6 x inches to 96 inches in width and 48 inches to 96 inches in length. Thicknesses range from 3/16 to 1-1/2 inches. Plate widths typically range from 48 to96 inches, while plate lengths range up to 300 inches. Angles are available in full and equal leg lengths, both in standard sizes and custom cuts. Rounds and squares can be ordered in bar lengths up to 18 inches. Standard sizes are available for flats and pipes.
The atmospheric corrosion resistance of ASTM A588 Grade B is considerably better than that of carbon steels such as A36 and A572-50 with or without copper addition. When properly exposed to the atmosphere, it displays greater corrosion resistance than other steel grades. The atmospheric corrosion resistance of ASTM A588 Grade B is substantially better than that of carbon steels such as A36 and A572-50 with or without copper addition. When properly exposed to the atmosphere, it displays enhanced resistance to atmospheric corrosion compared to other steels. Its ability to resist corrosion depends on the thickness and composition of the material as well as the environmental conditions. Furthermore, it exhibits good resistance to environmental influences such as moisture, wind, and chemicals.
When specifying ASTM A588 Grade B steel for any structural application, it is important to be aware of theASTM A588 Grade B standard sizes to ensure that the material is ordered in the correct shape at the right amount. With its excellent properties and versatility, it can be used for a variety of applications.
