The chemical composition is restricted to ensure weldability and prevent cracking during welding processes. Key elements monitored include:
EN 10225-1 is a European Standard that defines the requirements for the chemical composition, mechanical properties, and testing methods of steel products, including plates, strips, and sections. The standard is titled "Weldable structural steels for fixed offshore structures - Part 1: Plates" and is published by the European Committee for Standardization (CEN).
The North Sea and Arctic regions can reach sub-zero temperatures. Standard structural steel can become brittle in the cold. EN 10225-1 mandates rigorous Charpy V-notch impact testing to ensure the steel remains ductile and absorbs energy without fracturing, even at temperatures as low as -40°C or lower depending on the grade.
is the European standard specifying the technical delivery conditions for weldable structural steel plates used in the fabrication of fixed offshore structures. It provides a rigorous framework for high-strength steels designed to withstand the harsh environmental conditions typical of the North Sea and similar offshore sectors. Scope and Application
