EN 10025-2 S355JR Hot Rolled Steel Plate with 355 MPa Yield Strength EN 10025-2 Certified and 27 J Impact Toughness

• High Strength-to-Weight Ratio: With a yield strength of 355 MPa, it enables lighter structures without sacrificing load-bearing capacity, reducing material costs in bridges and high-rise buildings.
• Good Toughness: Tested at +20°C with 27 J impact energy, S355JR performs reliably in standard environments, suitable for general structural use.
• Excellent Weldability: Low bon equivalent (CEV ≈ 0.45) allows welding without preheating in many cases, facilitating efficient fabrication for large structures.
• Atmospheric Corrosion Resistance: Additions of silicon and copper provide better resistance to weathering, making it suitable for outdoor applications like offshore platforms.
• Cost-Effectiveness: Offers higher strength than S275J2 or S235J2 steel, allowing for material savings while maintaining performance.
• Compliance and Certification: Meets DIN EN 10025-2 and BS EN 10025-2 material grade requirements, with CE marking and EN 10204 3.1/3.2 certificates available.

S355JR exhibits excellent weldability due to its low bon equivalent, compatible with standard processes like SMAW, GTAW, and SAW. Key considerations:

• Preheat: Minimal or no preheating required for plates up to 25 mm, reducing fabrication time.
• Post-Weld Heat Treatment (PWHT): Not typically needed, but recommended for thicker plates (>40 mm) to relieve stresses.
• Filler Materials: Use low-alloy fillers matching the strength of S355JR, such as E7018 or ER70S-6.
• Fabrication: High ductility (20% elongation) supports bending, rolling, and forming for complex structural components.

GNEE supplies S355JR in normalized conditions, enhancing grain refinement for improved fabrication performance.

S355JR's high load-bearing capacity makes it an indispensable component in engineering projects:

• Building Structures: Columns for high-rise buildings, industrial plant frames, and roof trusses.
• Infrastructure: Support components for highway bridges, railway bridges, and pedestrian walkways.
• Heavy Machinery: Chassis for excavators and loaders, crane booms, and mining crusher supports.
• Energy Equipment: Transmission towers, wind turbine tower foundation components, and pressure vessel supports.

• Surface Treatment: We offer sandblasting (Sa2.5 standard) and shop primer coating to effectively prevent oxidation and corrosion during transit and storage.
• Custom Cutting: Equipped with CNC laser, plasma, and flame cutting machines, maintaining tolerances within ±1.0mm.
• Quality Traceability: Every batch is accompanied by an EN 10204 3.1 Mill Test Certificate (MTC), with unique Heat Number hard stamping on each plate.
• Logistics: Standard export packaging is utilized. For sea freight, anti-rust oil coatings and waterproof woven bags are applied to ensure a pitting-free surface upon delivery.
