Grade S460ML is a kind of weldable fine grain structural steel under EN 10025-4. The Material number is 1.8838. EN 10025-4 S460ML Steel: thermomechanical rolled structural steel (S) with a specified minimum yield strength at ambient temperature of 275 MPa, and with a specified minimum value of impact energy at -50°C.
EN 10025-4 standard is a requirement for long products and hot rolled flat products from weldable fine grain structural steels in state after normalization or normalization rolling, thickness ≤ 250mm for steel grade S275, S355, S420 and thickness ≤ 200mm for steel grade S460. The given steels are intended for particularly loaded elements for weldable structures such as bridges, lock gates, storage tanks, and water tanks, used at ambient temperate and in low temperates. Structural steels must be referenced using standard symbols including but not limited to: M, ML.
