SPA-H corten steel is a copper chromium alloy steel. SPA-H corten steel composition especially the added alloy elements display a greater level of resistance to atmospheric weathering when compared to other unalloyed steels. SPA-H corten steel composition promotes the early formation of an adhering protective layer of rust when exposed to the atmosphere.
SPA-H corten steel 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 |
Besides, the SPA-H corten steel properties are decided by SPA-H corten steel composition to large extent.
SPA-H corten steel properties:
| Symbol | Thickness(mm) | Yield point or proof stress N/mm² (min) |
Tensile strength N/mm² min |
Elongation % min |
| SPA-H | ≤ 6.0 | 345 | 480 | 22 |
| >6.0 | 355 | 490 | 15 |
SPA-H corten steel is available in a wider variety of shapes, thickness, and dimensions. SPA-H corten steel is widely used in air preheater, economizer, railway carriage, containers production, bridge building, construction and so on.
