    Abstract

    Weathering steel (ASTM A588, Grade B) and steels with 0.021 and 0.21 percent copper were tested for corrosion resistance in marine, rural, and two industrial environments. The results of these tests are represented well by kinetic equations of the form C = AtB, where C is the corrosion loss, t is time, and A and B are constants. On the basis of the time required to achieve a 250-μm (0.01 in.) thick ness loss that is calculated using these equations, the weathering steel is 6 to 19 times more durable than the 0.021 percent copper steel and 2 to 10 times more durable than the 0.21 percent copper steel.
