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 S315MC
Min. Yield strength  ReH1 (N/mm²)   315
Tensile strength Rm (N/mm²)   400 - 500
Elongation (%) t < 3 24
3 ≤ t < 5 33

1. Upper yield strength or 0.2% proof stress applies.
Elongation after fracture A uses test piece length L0 = 80 mm for t < 3 mm. L0 = 5.65√S0 for t ≥ 3 mm.
t – material thickness in mm.
 

Impact strength

Impact tests can be performed for thicknesses ≥ 6.0 mm. Please contact us for details.
