Mechanical Properties

Steel supplied will comply with the mechanical property limits below.
All values are measured transverse to the rolling direction.

Tata Steel Grade Ympress E690TM
Min. Yield strength  ReH (N/mm²)   690
Tensile strength Rm (N/mm²)   750 - 950
Elongation (%) t < 3 12
3 ≤ t < 5 14
t ≥ 5 14
Min. bend test diameter t < 5 1.0 t
t ≥ 5 1.5 t
Upper yield strength or 0.2% proof stress applies.
t – material thickness in mm.
Elongation after fracture uses 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.
