Resumo
Driven by market trends, increasing environmental accountability, government regulations and fostered by the Company’s strategic plan, ArcelorMittal Tubarão has developed new steel products to deliver better solutions to fit each customer’s needs. This often translates in higher strength, more complex and dimensionally challenging (thinner and wider) steels to attend a broad array of goals, such as reduction of vehicles fuel consumption and carbon emissions, increase in fatigue performance of heat treated parts, higher load capacity per net weight in vessels or wagons and lower supplying lead time as ArcelorMittal Tubarão establishes itself as a domestic option for so far imported grades. Based on the annual Product Development Plan, a structured workflow involves technical discussions from an operational point of view about safety issues, metallurgical project, steel grade family definitions, offline simulations prior to field trials, deformation resistance and process parameters adjustments and scheduling strategy. As a result of the increasing synergy between the areas, the share of new materials developed in recent years has been sustainably increased up to 15% in 2018, adding value to the final product without impact on hot rolled coil output and with a low cobble index.
