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.

Normalized fine-grain structural steel with guaranteed -50°C impact toughness. Lower strength than S355NL but better weldability and ductility. Used for cryogenic-adjacent structures, LNG infrastructure, cold-climate bridges, and storage tanks where low-temperature toughness is critical.

Normalized 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.

Normalized fine-grain structural steel with 355 MPa yield and -50°C impact toughness. The most widely used fine-grain grade in EN 10025-3. Workhorse for offshore, bridges, cranes, and wind turbine towers in cold climates. Better low-temp toughness than S355J2.

High-strength normalized fine-grain structural steel. 420 MPa yield with -50°C impact toughness. Between S355NL and S460NL in the strength ladder. Used for bridges, crane structures, pressure vessels, and structural components in cold environments.

Highest-strength normalized fine-grain structural steel in EN 10025-3. YS 460 MPa with guaranteed weldability and impact toughness. Used for heavy crane structures, offshore platforms, bridges, and any high-load structure where normalized delivery is required.

High-strength normalized fine-grain structural steel with 460 MPa yield and impact testing at -50°C. The highest-strength grade in the EN 10025-3 normalized series. Used for offshore platforms, wind turbine towers, arctic bridges, cranes, and heavy steel structures in cold climates.
