Chemical composition meets the requirements of EN 10305.

If other chemical elements such as Ti, Nb or V are used, the content of these elements are reported in the inspection document.

¹⁾ This requirement is not applicable provided the steel contains a sufficient amount of other nitrogen binding elements, such as Ti, Nb or V.
