Mechanical Properties
Steel supplied will comply with the mechanical property limits below.
The values of the tensile test apply to test bars parallel to the rolling direction.
The values of the bend test apply to test bars transverse to the rolling direction.
| Grade | Tenform XF355 | |
|---|---|---|
| Min. Yield strength ReH1 | N/mm² | 355 |
| Tensile strength Rm | N/mm² | 430-550 |
| Min. elongation after fracture A% | t < 3 | 23 |
| 3 ≤ t < 5 | 26 | |
| t ≥ 5 | 23 | |
| Min. bend test diameter | t < 5 | 0.5 t |
| t ≥ 5 | 0.5 t |
1. Upper yield strength or 0.2% proof stress applies.
t – material thickness in mm.
Elongation test piece length L0 = 80 mm for t < 3 mm. L0 = 5.65√S0 for t ≥ 3 mm.
Impact strength
Impact tests can be performed for thicknesses ≥ 6.0 mm. Please contact us for details.
