ASTM A588GrB Steel Plates Supplier

A588M Gr (A, B, K) is a weathering steel for atmospheric corrosion-resistant high-strength low-alloy structural steel materials, and low-alloy high-strength steel products are hot-rolled sheets for buildings and bridges.

A588GrB steel plate execution standard: ASTM A588/A588M

A588GrB steel plate delivery status: hot rolled, normalized, tempered, normalized + tempered, quenched and tempered. Different delivery states can be selected according to different needs.

a588gra is equivalent to my country's: Q355NH

Chemical composition of A588GrA weathering steel sheet:
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

When the A588GrB steel plate is rolled, a protective layer is formed on the surface of the metal matrix through the alloying of Cu, P, Cr, N, etc., so that the A588GrB steel plate has high atmospheric corrosion resistance.
