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 DD14
Yield strength ReL  (N/mm2) 1.5 ≤ t < 2 170 - 310
2 ≤ t < 11 170 - 290
Max. tensile strength Rm  (N/mm2)   380
Elongation (%) 1.5 ≤ t < 2 31
2 ≤ t < 3 32
3 ≤ t < 11 36
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 DD14
C Max. 0.08
Mn Max. 0.35
P Max. 0.025
S Max. 0.025

All values are in weight%.
