Chemical composition meets or exceeds 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) SSAB Form Tube C grade is suitable for high quality hot-dip galvanizing (Si < 0.03%, Si+2.5P < 0.06%). SSAB Form Tube H grade is suitable for high quality hot-dip galvanizing (Si < 0.03%, Si +2.5 P < 0.06%)

2) Low level of impurities ensure excellent formability and weldability

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