Option 1: A steel grade not specified in this document with a maximum total content of alloying elements of
5 % and agreed chemical composition, mechanical properties and delivery condition, is specified. NOTE When subsequently welding tubes produced in accordance with this document account should be taken of the fact that the behaviour of the steel during and after welding is dependent not only on the steel composition and the delivery condition but also on the conditions of preparing for and carrying out the welding.

All appropriate measures shall be taken to prevent the addition of undesirable elements from scrap or other materials used in the steel making process. b This requirement is not applicable provided the steel contains a sufficient amount of other nitrogen binding elements, such as Ti, Nb or V. When using titanium, the manufacturer shall verify that (Al + Ti/2) ≥ 0,020. Additions of Nb, Ti and V are permitted at the discretion of the manufacturer. The content of these elements shall be reported. Option 2: The composition of the specified steel grade shall be such that it is suitable for hot-dip galvanizing (see e.g. EN ISO 1461 for guidance).
