S275N

1.0490

Carbon SteelFine Grain

Normalized fine-grain structural steel with 275 MPa yield. The lowest strength grade in the EN 10025-3 normalized series. Better weldability and guaranteed fine-grain structure compared to standard S275JR. Used for welded structures, bridges, and general steelwork where normalized delivery is specified.
