Mechanical properties
The values shown for the mechanical properties in the table below are for test pieces taken parallel to the rolling direction.
| Grade | DP800 | |
|---|---|---|
| Yield strength1 Rp0.2 | N/mm² | 450 - 560 |
| Tensile strength Rm | N/mm² | 780 |
| Elongation | % | 14 |
| Min. n-value (10% - Ag) | - | |
| Min. BH2 | N/mm² | 30 |
1. Yield strength refers to the 0.2% proof strength for the product.
Elongation after fraction A uses test piece length L0 = 80 mm.
