EN10225 S460G2+M Steel is a weldable structural steel for offshore engineering applications compliant with European standards. Its core applications and performance advantages are highlighted below:
1. Offshore Platforms and Coastal Structures
Applications: Manufacturing of critical load-bearing components for offshore oil platforms, including legs, piles, and brackets, as well as offshore wind turbine towers and port equipment.
Performance Support:
High Strength: Yield strength of 460 MPa and tensile strength of 530–700 MPa meet stringent load-bearing requirements for large-scale offshore structures.
Low-Temperature Toughness: Validated through -40°C Charpy impact tests to ensure structural stability in arctic marine environments.
Weldability: Delivered in thermomechanically rolled (TMCP) condition to guarantee weld seam quality and minimize crack risks.
2. Marine Vessels and Offshore Engineering Equipment
Applications: Used in ship decks, hull sections, pressure-resistant shells, and connectors for offshore engineering machinery.
Performance Support:
Fatigue Resistance: Fine-grained microstructure enhances resistance to fatigue crack propagation, extending equipment service life.
Corrosion Resistance: Alloying elements such as Cr and Mo improve pitting and crevice corrosion resistance in seawater environments.
3. Bridges and Heavy Steel Structures
Applications: Suitable for structures requiring high strength and impact resistance, such as sea-crossing bridges and heavy-duty cranes.
Performance Support:
Impact Resistance: High elongation (≥17%) and impact energy (≥60 J at -40°C) ensure safety under dynamic loading conditions.
Machinability: Supports cutting, bending, and other fabrication processes to accommodate complex structural designs.
