ArcelorMittal Flat Products produces a wide range of steel plates, including grades with the most demanding qualities for offshore applications in the energy sector.

ArcelorMittal’s goal is to offer the most comprehensive range of plates for the offshore energy market. Steel plates produced by Flat Products are typically utilised in the subsea and visible parts of offshore wind turbines, and oil & gas platforms.

Plates available in most common high-quality grades

Two of the most common grades used in these segments are S355 M/ML and SS355MLO in thicknesses ranging from 40 to 70 mm. The ‘M’ in the grade name indicates that the steel has been thermo-mechanically rolled. The process changes the properties of the steel and makes it suitable for use in applications where high strength and excellent toughness at low temperatures are required. That includes a variety of offshore applications such as the topsides of oil & gas platforms, offshore wind substations, and the subsea ‘jackets’ which serve as foundations for offshore structures.

One of the key features of ArcelorMittal’s offshore plate offer is its enhanced weldability. This ensures that the steel can be welded without affecting its high-strength or exceptional toughness.
