1. Introduction of A588GrB steel plate
A588GrB is suitable for high-strength low-alloy structural steel for welding, riveting or bolting, mainly for welding bridges and buildings, where it is very important to reduce weight or increase durability. In most environments, the atmospheric corrosion resistance of this steel is significantly better than that of carbon structural steel with or without copper added.
2. A588GrB steel plate implementation standard: ASTM A588/A588M
3. Delivery status of A588GrB steel plate: hot rolled, normalized, tempered, normalized + tempered, quenched and tempered. Different delivery status can be selected according to different needs.
4. Chemical composition of A588GrB steel plate
| Grade | C | Mn | P | S | Si | Ni | Cr | Cu | V |
| A588GrB | ≤0.20 | 0.75-1.35 | ≤0.030 | ≤0.030 | 0.15-0.50 | ≤0.50 | 0.40-0.71 | 0.20-0.40 | 0.01-0.10 |
5. Mechanical properties of A588GrB steel plate
| Grade | Thickness | Yield Strength ReH[N/mm2]transv.min |
TensileStrength Rm[N/mm2]transv |
| ASTM A588 | 0mm-100mm | 340 MPa | 480 MPa |
| 102mm-127mm | 320 MPa | 460 MPa | |
| 127mm-203mm | 290 MPa | 430 MPa |
6. Application scope of A588GrB steel plate
A588GrA, A588GrB, A588GrC These steels are used for welded, riveted and bolted structures, but are mainly used for welded bridges and buildings where weight reduction or extended life is required. This steel has significantly better atmospheric corrosion resistance than copper-containing or copper-free carbon structural steels in most environmental conditions. This steel is suitable for many applications in the bare (uncoated) state when fully exposed to the atmosphere.
