A588GrB steel is similar to the A588GrA, but better than it. Because the more content of Cr, A588GrB has the better property of atmospheric corrosion resistance.when properly exposed to the atmosphere,this steel is suitable for many applications in the bare and unpainted.
Through the element of Cu、P、Cr、Ni, A588GrB can form the protection layer on the face of the steel, which makes the higher weathering corrosion. A588GrB is widely used to various parts of building structure and bridge structure.
