S460ML
1.8838Thermomechanically rolled fine-grain structural steel — ReH >=460 MPa with Charpy at -50°C (KV >=27J). TM rolling = fine grain without normalizing = higher strength at lower CEV = better weldability than S460N. Used for offshore jackets, heavy crane booms, bridges in cold climates, and large welded structures needing high strength + low-temp toughness.
