Mechanical properties
The values shown for the mechanical properties in the table below are for test pieces taken transverse to the rolling direction:
| EN 10111: 2008 | Grade | DD13 |
|---|---|---|
| Yield strength ReL (N/mm2) | 1.5 ≤ t < 2 | 170 - 330 |
| 2 ≤ t < 11 | 170 - 310 | |
| Max. tensile strength Rm (N/mm2) | 400 | |
| Elongation (%) | 1.5 ≤ t < 2 | 28 |
| 2 ≤ t < 3 | 29 | |
| 3 ≤ t < 11 | 33 | |
| Min. bend test diameter | 0t |
Values are for test pieces taken transverse to the rolling direction:
t - material thickness in mm
Lower yield strength or 0.2% proof stress applies.
Test piece length L0 = 80mm for thicknesses <3mm and L0 = 5.65√S0 for thicknesses ≥3mm
Chemical composition
Hot-rolled steel for forming meets the requirements of the cast analysis in the standard as shown in the table below:
| EN 10111: 2008 | Grade | DD13 |
|---|---|---|
| C | Max. | 0.08 |
| Mn | Max. | 0.4 |
| P | Max. | 0.03 |
| S | Max. | 0.03 |
All values are in weight%.
