A588 Gr.A high weathering bridge structural steel

A588 Gr.A is an American standard high weathering bridge structural steel plate, and it is also a high-strength low-alloy steel that is resistant to atmospheric corrosion in accordance with ASTMA 588/A588M-05.

A588 Gr.A steel plate executive standard: ASTM (American Standard)
A588 series steel plate: A588 Gr.A, A588 Gr.B, A588 Gr.C.

A588 Gr.A steel plate delivery status: hot-rolled, normalized, tempered, normalized + tempered, quenched and tempered; different delivery conditions can be selected according to different needs.

A588Gr.A steel plate thickness direction performance requirements: Z15, Z25, Z35.

A588 Gr.A Chemical Composition:
C:≤0.19
Si: 0.30-0.65
Mn: 0.8-1.25
P:≤0.03
S:≤0.03
V: 0.02-0.1
Cr: 0.4-0.65
Ni: ≤0.4
Cu: 0.25-0.4
Through the alloying of Cu, P, Cr, Ni, etc., a protective layer is formed on the surface of the metal substrate, so that it has high atmospheric corrosion resistance.
