Mechanical Properties
The mechanical properties of Durbar® comply with EN 10025-2: 2004 and are shown in the table below. The values shown for strength and elongation are for test pieces taken transverse to the rolling direction; those for the impact test are for test pieces taken in the rolling direction.

|---|---|---|
| Min. yield strength1 ReL (N/mm2) | 275 | |
| Tensile strength Rm (N/mm2) | 410 - 560 | |
| Elongation % | 3 ≤ t ≤ 12.5 | 21 |
| Impact strength | Temp. °C | 20 |
| Min. energy J | 27 |
1. Lower yield strength or 0.2% proof stress applies.
t - material thickness in mm.
Impact tests can be performed for thicknesses ≥ 6.0 mm. Please contact us for details.
Elongation after fracture A uses test piece length L0 = 5.65√S0.
