Thermo-mechanically controlled rolled, weldable fine-grain structural steel designed for heavy welded constructions and low-temperature service. EN 10025-4 S355ML provides high yield strength (typically around 355 MPa) combined with good toughness and excellent weldability, making it suitable for demanding structural and load-bearing applications.

Supply notes
Material is supplied in the TMCP (thermo-mechanically rolled) condition in the listed plate, sheet and bar formats. Typical purchasing enquiries on dimensions, mill certifications and processing options (cutting, surface treatment, testing) should specify required tolerances and application to ensure the correct plate grade and delivery condition.
