a588 grade b weather steel equivalent for sale

A588 Grade B is a high-strength low-alloy steel (HSLA) that is commonly used in structural applications. It has good atmospheric corrosion resistance which makes it suitable for many outdoor applications. However, due to its relatively low composition of alloy elements, A588 Grade B weather steel has limitations in its mechanical properties when compared to other weathering steel grades.

Equivalent Grades of A588 Grade B Weather Steel

A588 Grade B is the ASTM designation for this material. It is equivalent to Corten B, which is a weathering steel that is also commonly used in structural applications. Other equivalent grades include S355JOWP, SMA490BW, and WR50B, among others.

Mechanical Properties of A588 Grade B Weather Steel

A588 Grade B has a minimum yield strength of 50 ksi (345 MPa) and a minimum tensile strength of 70 ksi (483 MPa). It has a high resistance to stress corrosion cracking and can be welded using conventional welding methods. However, it is important to ensure that the welding is performed with low hydrogen electrodes to prevent hydrogen-induced cracking.

Applications of A588 Grade B Weather Steel

A588 Grade B weather steel is used in many applications where high strength and good corrosion resistance are required. Some common applications include:

1. Bridges: A588 Grade B is commonly used in bridge construction due to its high strength and resistance to atmospheric corrosion.

2. Buildings: A588 Grade B is also used in building construction, particularly in applications where the building is exposed to the elements.

3. Railcars: A588 Grade B is used in the construction of railcars due to its high strength and good resistance to atmospheric corrosion.

4. Tanks: A588 Grade B is used in the construction of tanks and other structures that need to be resistant to corrosion.

In conclusion, A588 Grade B weather steel is a high-strength low-alloy steel that is commonly used in structural applications. It has good atmospheric corrosion resistance, but limited mechanical properties when compared to other weathering steel grades. A588 Grade B is equivalent to Corten B and has a minimum yield strength of 50 ksi (345 MPa) and a minimum tensile strength of 70 ksi (483 MPa). Its applications include bridge construction, building construction, railcars, and tanks, among others.
