: Permitted up to 150 mm thick. 📊 Major Steel Grades and Property Designations
The standard limits heat input (typically ≤ 5.0 kJ/mm for S355G). Your WPS must qualify using CTOD tests per EN 10225 Annex A.
Always purchase from an authorised source to guarantee you are working with the correct, complete, and legally permissible standard.
Yes. Part 1 includes providing informative guidance on prequalification of steels for fixed offshore structures operating in arctic areas. For temperatures below –40 °C, additional testing and specification may be required . en 102251 pdf
