What is S355ML Steel EN 10025-4 Hot Rolled Plate?

S355ML is a hot rolled, thermomechanically rolled (TMCP), weldable fine-grain structural steel according to EN 10025-4:2004 (current version 2019).

Key features:

• Minimum yield strength 355 MPa
• Excellent low-temperature toughness: ≥ 27 J at –50 °C (longitudinal)
• Very low CEV ≤ 0.39 → outstanding weldability (no preheat up to 80 mm)
• Fine grain structure from TMCP process
• Ideal for weight-critical and cold-environment structures

S355ML is the hot rolled TMCP version of S355J2 + improved toughness. It is the most demanded grade in EN 10025-4 for offshore wind towers, Arctic pipelines, jack-up rigs, heavy cranes, and cold-region bridges.
