1) Applies to upper yield strength ReH.
2) Except for S550GD steel grade, the span of tensile strength is 140 MPa.
3) Depending on the product thickness, the minimum elongation at break decreases as follows: 0.50 mm < t < 0.70 mm (minus 2 units), 0.35 mm < t < 0.50 mm (minus 4 units) and t < 0.35 mm (minus 7 units) units).
