EN 10025-4 S275ML Steel

High-strength, weldable fine-grain structural steel produced to EN 10025-4. This thermo-mechanically rolled plate grade provides a guaranteed minimum yield strength of 275 MPa at ambient temperature (S275ML) and is specified with impact requirements down to low temperatures specified in EN 10025-4 (commonly -50°C for this family of grades). Designed for structural applications where a combination of strength, toughness and weldability is required.

Key specifications

• Standard: EN 10025-4
• Grade: S275ML (thermo-mechanically rolled structural steel)
• Guaranteed minimum yield strength: 275 MPa (ambient temperature)
• Impact performance: specified minimum impact energy at low temperature per EN 10025-4
• Rolling / production: Thermo-Mechanical Control Process (TMCP)
• Typical form: flat plates
• Thickness range: 5 mm – 150 mm
• Width range: 1,500 mm – 4,200 mm
• Length range: 3,000 mm – 18,000 mm
• Surface / tolerances: to EN 10025 series dimensional and tolerance requirements

Features and benefits

• Good weldability for common structural welding processes
• Fine-grain microstructure from TMCP giving improved toughness
• Suitable for welded construction where predictable mechanical performance is required

Typical applications

• Structural steelwork for buildings and bridges
• Heavy fabrication: cranes, trailers, lifting equipment
• Offshore and onshore steel structures requiring controlled toughness
• General engineering components where higher-than-basic structural strength is needed

Supply and ordering

• Plates can be supplied in full lengths or cut-to-size; additional processing (plasma/oxy cutting, drilling, edge preparation) typically available from industrial suppliers — confirm when placing your RFQ
• Mill Test Certificates (MTC) and mechanical/chemical test reports can be supplied on request to demonstrate compliance with EN 10025-4

For procurement, include required dimensions, plate quantity, required certification and any secondary processing in your RFQ so suppliers can provide accurate quotations.
