EN10025 S460M Structural Steel Plate Supplier

EN10025 S460M Structural Steel Plate Supplier

Gangsteel – China’s Largest Mill-Direct Supplier & Exporter of EN10025 S460M Structural Steel Plates

Gangsteel is the professional supplier you can trust for EN10025 S460M structural steel plates, with the largest permanent stock in Asia – over 5,000 tons always ready in thickness 6–200 mm, width 1500–4200 mm, length up to 18 meters. All plates are genuine TMCP (thermomechanical controlled process) produced by top mills with full European approvals and third-party inspection (DNV-GL, ABS, LR, BV, CCS, KR, TÜV, SGS).

EN10025 S460M is the high-strength grade in the en 10025 4 High Strength Structural Steel family, offering 460 MPa minimum yield strength and ≥40 J impact toughness at –20 °C. It is the direct TMCP alternative to normalized S460N (EN 10025-3) and the sister grade to the low-temperature bestseller S460ML (–50 °C).

We also stock the complete EN 10025-4 series, including the popular low-temperature grade en 10025 4 s460ml steel plate and the widely used en 10025 4 s355ml steel plate, as well as the standard-temperature en 10025 4 s355m steel plate.

What is EN10025 S460M Structural Steel Plate?

EN10025 S460M is a thermomechanically rolled (TMCP) weldable fine-grain structural steel specified in EN 10025-4:2004 (current version 2019).

The designation “S460M” means:

• S= structural steel
• 460= minimum yield strength 460 MPa (transverse, thickness ≤ 16 mm)
• M= thermomechanical rolling (TMCP delivery condition)

The TMCP process gives EN10025 S460M superior properties compared to normalized grades:

• Higher strength-to-weight ratio
• Lower residual stress
• Better flatness and dimensional stability
• Excellent weldability (CEV ≤ 0.48)
• Better fatigue performance and HAZ toughness

EN10025 S460M is the highest-strength standard-temperature grade in the EN 10025-4 family. It is the direct TMCP alternative to normalized S460N (EN 10025-3) and the sister grade to the low-temperature bestseller S460ML (–50 °C).

EN10025 S460M plates are widely used in structural applications requiring maximum strength without extreme low-temperature demands, such as high-rise building columns, heavy crane booms, lifting equipment, and onshore wind turbine towers. The material's fine grain structure from TMCP ensures consistent performance even in thick sections, making it ideal for cost-effective designs under Eurocode 3 (EN 1993-1-1).

Gangsteel's EN10025 S460M plates are produced with ultra-low sulfur (S ≤ 0.010%) for Z35 quality, ensuring no lamellar tearing in critical welded joints. Our plates have typical actual yield strengths 10–20% above minimum, providing an extra safety margin.

Chemical Composition – Ladle Analysis (max % unless noted)

Typical Gangsteel actual values: C 0.10–0.14 %, CEV 0.42–0.46 → excellent weldability without preheating up to 80 mm thickness.

Mechanical Properties – Full Thickness Range up to 200 mm (transverse values)

*Gangsteel guarantees higher values in thick plates by agreement.

Applications of EN10025 S460M Plates

EN10025 S460M is widely used when maximum strength is required:

• High-rise building columns
• Heavy crane booms and lifting equipment
• Onshore wind turbine towers
• Heavy machinery bases
• Shipbuilding and marine structures (non-Arctic)

When the temperature drops below –20 °C, the low-temperature version S460ML is required.
