SPA-H Corrosion Resistant Steel Plate
SPA-H steel material can be produced as SPA-H steel plate, SPA-H steel sheet, SPA-H steel bar, SSPA-H section steel, SPA-H structural shapes. SPA-A steel all made of carbon steel and copper, nickel, phosphorus and other chemical elements.
The content of these chemical elements, only a few percent. Because different alloying elements, weather resisting steel has better mechanical properties, as well as greater corrosion resistance. Thus, SPA-A steel used for marine containers, container, bridges, and train tracks.
SPA-H Weathering steel chemical composition:
| Grade | C ≤ | Si | Mn | P | S ≤ | Cu | Cr | Ni ≤ |
| SPA-H | 0.12 | 0.25~0.75 | 0.20~0.50 | 0.070~0.150 | 0.04 | 0.25~0.60 | 0.30~1.25 | 0.65 |
SPA-H Weathering resistant steel mechanical properties:
| Grade | Plate Thickness | Yield strength | Tensile strength | elongation |
| SPA-H | 6.0mm max | min 345 MPa | min 480 MPa | min22 |
| 6.0mm min | min 335 MPa | min 490 MPa | min 15 |
