Basic properties of A588 GrB steel plate

A588 GrB steel plate is a high weathering bridge structural steel plate, which belongs to the American standard steel plate and implements the American standard ASTM standard. When the A588 GrB steel plate is rolled, a protective layer is formed on the surface of the metal substrate through the alloying of Cu, P, Cr, N, etc., so that the A588 GrB steel plate has high atmospheric corrosion resistance.

Chemical composition of A588 GrB steel plate (melting analysis %):
C: not more than 0.20,
Mn:0.75-1.25,
P is not greater than 0.04,
S is not greater than 0.05,
Si: 0.15-0.50,
Ni is not greater than 0.50,
Cr: 0.40-0.70,
Cu:0.20-0.40,
V: 0.01-0.1

Mechanical properties of A588 GrB steel plate: tensile strength MPA: not less than 485, yield strength MPA: not less than 348, elongation after fracture: not less than 21

Delivery status of A588 GrB steel plate: hot rolled, normalized, tempered, normalized + tempered, quenched and tempered. Different delivery states can be selected according to different needs.

Smelting method of A588 GrB steel plate: Steel should be smelted by fine grain process.

Detailed specifications of A588 GrB steel plate:
Thickness: 8-200mm, Width: 1500-4020mm, Length: 6000-18800mm.

A588 GrB steel plate is often used in construction, workshop, bridge auxiliary, construction machinery, etc. to manufacture electric wheel dump trucks, mining vehicles, excavators, loaders, bulldozers, cranes, coal mine hydraulic supports and other mechanical equipment and structural parts.
