A588 Grade B weathering steel plate rolling

 A588M Gr (A, B, K) is a high-strength low-alloy structural steel with atmospheric corrosion resistance
Material Category: Weathering Steel, Low Alloy High Stren

product description

A588M Gr (A, B, K) is a high-strength low-alloy structural steel with atmospheric corrosion resistance
Material Category: Weathering Steel, Low Alloy High Strength Steel Products, Hot Rolled Sheets
Uses: 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.
