S460ML construction steel is a thermo-mechanically rolled material which has a yield strength of a minimum of 450 N/mm2. S460ML has been impact tested as low as -50°C and is produced in accordance with the European designation EN10025-4 (TMCP).
Chemical Composition of S460ML
Applications of S460ML
S460ML is fine grain meaning it can be easily-welded. Owing to its reduced carbon content and low carbon equivalent value, it can be deployed in all known welding processes and is commonly used by in both automatic and manual welding applications.
Using S460ML for structural sections can offer a number of benefits for high-rise/multi-storey buildings it has a well-balanced cost and efficiency. The strength and light weight of S460ML means the size of the structural sections, particularly columns, can be reduced. The buildings become lighter, with a weight reduction of 10-30% when using S460 (65 ksi) instead of S355 (50 ksi): 15% for columns, 20-35% for trusses. However, structural safety is not negatively impacted but this weight reduction.
S460ML is also used for medium or short span beams for bridges, chord, and diagonal members of trusses, pipelines, plater girders, pressure vessels and road tankers. It is easy to weld, process, and bend both on site and in workshops.
S460ML has a high tensile strength, meaning it is is hard-wearing whilst also having a good stretch-flangeability allowing thinner steel plates to be used and thus reducing the amount of welded joints. These attributes result in the production of environmentally sound, durable and smart structures.
Contrasting with all other structural specifications under EN10025, there are no direct equivalents in ASTM or Shipbuilding (ABS/BV/LR) designations to S460ML.
