S355ML is a hot-rolled, weldable fine-grain structural steel specified by the EN 10025-4 standard. The "S355" indicates a minimum yield strength of 355 MPa for thicknesses under 16mm, while "ML" signifies that it is a thermomechanical rolled product with a specified minimum impact energy of at least 27J at temperatures not lower than -50∘C.
