ASME SA588 Grade B corten steel weathering steel plates are usually used in structural applications such as bridges and buildings. The advantage of ASME SA588 Grade B corten steel over mild steel and common low alloy steel is its "weathering" ability, which provides atmospheric corrosion resistance and ultimately longer life in applications where exposure to the air.
ASME SA588 Grade B corten steel weathering steel plates chemical composition:
| Grade | C | Mn | P | S | Si |
| SA588 Grade B | ≤0.20 | 0.75-1.35 | ≤0.04 | ≤0.05 | 0.15-0.50 |
| Cu | Ni | Cr | V | ||
| 0.20-0.40 | ≤0.50 | 0.4-0.70 | 0.01-0.10 |
ASME SA588 Grade B corten steel weathering steel plates mechanical property:
| Grade | Yield Strength (MPa) min. | Tensile Strength (MPa) min. | Elongation in 8 in. min. % | Elongation in 2 in. min. % |
| SA588 Grade B | 315 | 460 | - | 21 |
The ASME SA588 Grade B corten steel weathering steel plates are used to manufacture plant, general building and all kinds of engineering machinery, such as drilling rig, electric shovel, electric wheel dump truck, mine car, excavator, loader, bulldozer, crane, coal mine hydraulic support and other mechanical equipment and other structural parts.
