Explanations

1) If the chemical composition of the steel contains min. 0.020% aluminum, the upper limit of nitrogen is not applied.

2) For the calculation of Ceq, the formula %CE (IIW) = C+Mn/6+(C+Mo+V)/5+(Ni+Cr)/15 is used.

Explanations

1) For the qualities with "+N" in the quality code, "hot forming" and/or "normalizing" can be performed by the customer.

2) Tensile test values are valid for "transverse" test samples.

3) Impact test is not applied for products with a thickness less than 6 mm.

4) Impact test is done upon request.
