What is BS EN 10225‑3 - Weldable structural steels about?
BS EN 10225 is a series of European standards on weldable structural steels that discusses its technical delivery conditions.
BS EN 10225‑3 is the third part of a series of documents. BS EN 10225‑3 specifies requirements for weldable structural steels made of hot finished seamless and high frequency welded hollow sections to be used in the fabrication of fixed offshore structures.
Who is BS EN 10225‑3 - Weldable structural steels for?
BS EN 10225‑3 on Hot finished hollow sections is beneficial for:
- Welders/ fabricators
- Structural engineer
- Steel manufacturer
- Metallurgist
Why should you use BS EN 10225‑3 - Weldable structural steels?
Weldable structural steels are the steels that rely on quench and temper heat treatment to obtain very high strength are more susceptible to welding problems and require specific metallurgical expertise. BS EN 10225‑3 navigates you through the requirements, Manufacturing process, test methods for weldable structural steels made of hot finished seamless and high frequency welded hollow sections that help the user to build perfect weldable structural steels
Detailed guidance on the requirement of steel is provided in BS EN 10225‑3, which helps the manufacturer of manufacture the steel accordingly.
Inspection methods, types of documentation required are mentioned in BS EN 10225‑3, these formulations helps the user to inspect the work and ensure high quality.
What’s changed since the last update?
BS EN 10225‑3:2019 together with EN 10225-1:2019, EN 10225-2:2019, and EN 10225-4:2019 supersede EN 10225:2009.
In comparison to the previous edition following technical changes were made
- All grades stronger than a SMYS of 355 Mpa are quenched and tempered
- The higher-strength normalized grades from EN 10210‑1:2006 (S420NH and S460NH) are not perpetuated in the offshore standard
- Former grades of group 3 are no longer listed, new options with the same enhanced properties have been introduced
