What is S460M Material EN 10025-4 Fine Grain Steel?

S460M material 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 fine grain structure is achieved through controlled microalloying (Nb, V, Ti) and the TMCP process, resulting in ASTM grain size 8–11. This is what gives S460M its excellent combination of very high strength, superior weldability, and good low-temperature toughness (≥40 J at –20 °C).

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).

Applications of S460M Fine Grain Material

S460M is widely used when maximum strength and good toughness are 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 – Quick Answers

Q1: What makes S460M "fine grain"?A: The combination of low carbon, Al + Nb + V + Ti microalloying, and TMCP process produces ASTM grain size 8–11, which is the definition of "fine grain" and the reason for its superior toughness and weldability.

Q2: S460M vs S460ML difference?A: Only impact test temperature. S460ML = –50 °C (≥27 J), S460M = –20 °C (≥40 J). Strength, chemistry, weldability identical.

Q3: Preheating required?A: No preheat up to 80 mm thickness. >80 mm: 75–100 °C max.

Q4: Z35 availability?A: Yes – very large stock of S460M + Z35 ready for immediate delivery.

Q5: Density and hardness?A: Density 7.85 g/cm³, hardness 160–210 HBW.

Q6: NDT standard?A: 100 % UT EN 10160 S2/E2 included. S3/E3, MT, PT on request.

Q7: Maximum thickness?A: Up to 200 mm with full properties and certification.
