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.

Tata Steel Grade Ympress S960MC
Min. Yield strength  ReH1 (N/mm²)   960
Tensile strength Rm (N/mm²)   1010 - 1250
Elongation (%) t < 3 -
3 ≤ t < 5 8
t ≥ 5 8
Min. bend test diameter t < 5 6.0 t
t ≥ 5 6.0 t 2
1. Upper yield strength or 0.2% proof stress applies.
2. For Ympress S960MC minimum bend test diameter is 8.0 t for t > 8 mm
t – material thickness in mm.
Elongation after fracture A 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.
