Mechanical properties
Cold-rolled structural steel has the following mechanical properties (skin-passed) - these are measured transverse to the rolling direction:
| Grade | CA240 | |
|---|---|---|
| Yield strength 1 | N/mm2 | 240 - 300 |
| Tensile strength | N/mm2 | 340 - 400 |
| Elongation | % | 28 |
1. Lower yield point or 0.2% proof stress applies.
Elongation after fracture A uses test piece length L0 = 80 mm.
There are no direct EN standard equivalents.
Chemical composition
Cast analysis in weight percentages:
| Grade | CA240 | |
|---|---|---|
| C | Max. | 0.085 |
| Mn | Max. | 0.55 |
| P | Max. | 0.03 |
| S | Max. | 0.03 |
| Alsol | Min. - Max. | 0.020 - 0.080 |
1. These additional elements may be used individually or in combination where they appear in the definition of the steel within the composition limits indicated. Vanadium and boron may also be added. However, the sum of the contents of these four dispersoidal elements shall not exceed 0.22%.
All values are in weight%.
