EN 10225 S460G5 + Q Introduce
The main motivation of this EN 10225 standard was to create a unified and reliable set of procedures and requirements when constructing offshore structures such as offshore platforms or oil rigs. The S355G2+N steel grade is used in applications ranging from equipment used on platform and topsides to mooring piles, anchor chains, and risers. This steel grade offers excellent corrosion resistance, high tensile and yield strength, and fatigue strength.
Smelting temperature:1257°C - 1961°C
