1) Where yield strength is defined, the values apply to the upper yield strength ReH.

2) For all steel types, with the exception of S550GD, a span of 140 MPa can be expected for the tensile strength.

3) Depending on the product thickness, the minimum values of elongation at fracture are reduced 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).
