TTV (Thickness Toughness Validator) is a tool developed internally by ArcelorMittal Steligence® Engineering. It is a simple tool for validating the selection of toughness subgrades according to the recommendations and requirements of the EN 1993-1-10 standard. This standard provides design guidance for the selection of steel for fracture toughness, imposing maximum detail thicknesses depending on material, temperature, and load level. The simplified method (EN 1993-1-10, Clause 2.3) is based on a simple table check. As it is general, it is based on safe assumptions that may not always correspond to specific project specifications. The advanced method (EN 1993-1-10, Clause 2.4), based on more advanced fracture mechanics methods, has therefore been implemented in order to perform a more specific check to deliver more advanced results. This tool is entirely based on Eurocode background methods and their application. As such, the advanced method will deliver the same results as the tables of the simplified method if the same assumptions are introduced. The user guide and validation examples are provided in the tool’s download folder.

The aim of this tool is to disseminate structural design knowledge and techniques for a subject that is often less known to designers. With TTV, the process of verifying steel details according to toughness requirements will be easier and will speed up workflow. Moreover, TTV includes advanced methods permitted by design standards, giving the user additional choices for verification methods.

ArcelorMittal, the world’s leading steel and mining company, is now producing low carbon emissions steel plate of up to 18 tonnes. ArcelorMittal is the first producer in Europe able to manufacture low carbon emissions steel plate in these dimensions.

XCarb® recycled and renewably produced Heavy plates are manufactured using slabs from ArcelorMittal Industeel and are produced in an electric arc furnace using almost 100% scrap steel and 100% renewable electricity. These slabs are then transformed in ArcelorMittal’s heavy plate mill in Asturias, Spain resulting in a significant reduction in CO2 emissions - approximately 60% lower compared with steel plate made via the conventional steelmaking route (blast furnace).

A lower carbon footprint for infrastructure projects

Eighteen-tonne heavy plate steel is typically used in major infrastructure projects - for example, in the welded sections and box girders for road and rail bridges. Using XCarb® recycled and renewably produced steel plate in civil engineering projects allows ArcelorMittal’s customers to demonstrably reduce their scope 3 emissions (supply chain emissions) and contribute to a lower carbon footprint for infrastructure projects.

Speaking about the launch of the new XCarb® solution, Denis Parein, Commercial Head Heavy Plate Europe at ArcelorMittal, said: “We are immensely proud to now be able to offer heavy plate to our customers with a CO2 footprint reduction of around 60% compared with the same product made using the conventional primary steelmaking route. Our teams have worked very hard to bring this product to market, which we know meets a growing customer need for low carbon emissions steel to reduce the carbon footprint of complex civil engineering projects. An EPD (Environmental Product Declaration), verified by a third party according to the EN 15804 European Standard, will be available for XCarb® recycled and renewably produced Heavy plates by the end of the year.”

ArcelorMittal Europe has a target to reduce CO2 emissions by 35% by 2030 and to reach carbon neutrality by 2050.
