Grade S460M EN 10025-4 High Strength Supplier

Grade S460M EN 10025-4 High Strength Supplier

Gangsteel – China's Leading Mill-Direct Supplier & Exporter of Grade S460M EN 10025-4 High Strength Plates

Gangsteel is the professional supplier you can trust for grade S460M EN 10025-4 high strength 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).

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 Grade S460M EN 10025-4 High Strength Plate?

Grade 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 – controlled hot rolling + accelerated cooling – produces a very fine-grained microstructure without separate normalizing heat treatment. This gives S460M:

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

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).

S460M plates are widely used in 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 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)

The chemical composition of S460M is carefully controlled to ensure excellent weldability and consistent properties across thicknesses.

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 EN 10025-4 S460M Plates

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.

FAQ – Detailed Answers

Q1: What is the difference between S460M and S460ML?

A: The only difference is the impact test temperature. S460M is tested at –20 °C with minimum 40 J (longitudinal), while S460ML is tested at –50 °C with minimum 27 J. Yield strength, tensile strength, elongation, chemical composition, and weldability are exactly the same. Choose S460M when service temperature is above –20 °C; choose S460ML when below –20 °C.

Q2: Is preheating required when welding S460M?

A: No preheating is required up to 80 mm thickness thanks to the very low CEV (typically 0.42–0.46 actual). For thicknesses over 80 mm or highly restrained joints, a modest preheat of 75–100 °C is sufficient.

Q3: Do you have Z35 quality in stock for S460M?

A: Yes – we keep very large stock of S460M + Z35 (reduction of area ≥35 % per EN 10164 Class 3), especially in 20–150 mm thickness, ready for immediate delivery.

Q4: What is the density and hardness of S460M?

A: Density is 7.85 g/cm³ (7850 kg/m³), hardness is 160–210 HBW (typical 170–190 HBW in our stock). These values are consistent across the entire thickness range.

Q5: What NDT do you provide as standard?

A: 100 % ultrasonic testing to EN 10160 S2/E2 is included with every plate. We can upgrade to S3/E3, magnetic particle (MT), or penetrant testing (PT) on request at no extra charge for reasonable quantities.

Q6: What is the maximum thickness you can supply for S460M?

A: Up to 200 mm with full properties and certification. We guarantee minimum yield of 380 MPa up to 180 mm and 350 MPa to 200 mm – significantly better than the standard requirement.

Q7: How fast can you deliver to Europe or USA?

A: From ready stock: 7–12 days to Rotterdam, Antwerp, Houston, or Los Angeles. We have regular consolidation containers and can offer air freight for urgent small quantities (<10 tons) in 48–72 hours.
