S355J2+N (Normalized Structural Steel – EN 10025-2) S355J2+N is a widely used non-alloy structural steel falling under the EN 10025-2 standard, valued for its high strength, excellent toughness, and ease of fabrication. It offers a minimum yield strength of 355 MPa, making it ideal for use in heavy-duty structures and industrial frameworks. The “J2” indicates that the material has passed Charpy impact testing at -20°C, ensuring it performs reliably in colder climates. The “+N” represents that the steel is delivered in a normalized condition, which refines the grain structure for improved mechanical performance and uniformity. Key Features: Minimum 355 MPa yield strength for demanding structural needs Certified impact resistance at -20°C, ideal for sub-zero climates Normalized rolling (+N) improves grain refinement and consistency Excellent fabrication characteristics, including welding and forming Mechanical Properties: Property S355J2+N Yield Strength ≥ 355 MPa Tensile Strength 470–630 MPa Elongation ≥ 19–22% Impact Resistance ≥ 27 J at -20°C Weldability Superior Applications: Civil engineering structures and industrial platforms Bridge construction and offshore modules Crane arms, lifting beams, and mechanical supports Steel fabrication in pressure vessels and load-bearing units Base frames, bracings, and welded parts in machinery Summary: With its combination of strength, impact toughness, and excellent workability, S355J2+N is ideal for structural applications exposed to dynamic loads and harsh conditions. It provides dependable performance for both indoor and outdoor industrial use.
