S355N
1.0545Normalized fine-grain structural steel. Same yield as S355JR/J2 but with guaranteed fine-grain structure from normalizing. Better weldability and impact toughness than standard S355. Used for bridges, cranes, heavy structural steelwork, and pressure vessels where normalized delivery is specified.
