A588GrA Weathering Steel Plate Performance Analysis

1 Chemical composition of A588GrA weathering steel plate:

C≤0.19 Si: 0.3~0.65 Mn: 0.8~1.25 P≤0.03 S≤0.03 Ni≤0.4

Cr: 0.4~0.65 Cu: 0.25~0.4 V: 0.02~0.1

2 8mm~200mm thick A588 series high weathering bridge structural steel plates include A588GrA, A588GrB, etc. A588GrA steel plate forms a protective layer on the surface of the metal substrate through the alloying of Cu, P, Cr, Ni, etc., so that it has high atmospheric corrosion resistance.

3A588GrA steel plate delivery status: hot rolled, tempered, normalized + tempered, quenched and tempered. Steel plates are produced by fine-grain smelting and other methods.
