a. Depending on the thickness of the product and the manufacturing conditions, the manufacturer may add to the steel one or several alloying elements up to the maximum
values given in order to obtain the specified properties (see 7.2.2).
b There shall be at least 0,015 % of a grain-refining element present. Aluminium is also one of these elements. The minimum content of 0,015 % applies to soluble
aluminium, this value is regarded as attained if the total aluminium content is at least 0,018 %; in case of dispute the soluble aluminium content shall be determined.
