Abstract:
This paper describes a cooperative project developed by Aperam South America (ASA) and Companhia Brasileira de Metalurgia e Mineração (CBMM) with the aim of completely replacing manganese with small concentrations of niobium in structural low carbon steels, like SAE/AISI 1012. The results got in the final product after Steckel rolling and delivery to partner customers showed the following advantages: potential cost reduction and improvement in microstructural refinement, homogeneity, and inclusionary cleanness, while keeping the same level of mechanical properties. This project allows ASA to include in its product mix an alloy that innovates the design for structural steels. Besides that, this alloy broke ground for the replication of this concept in other structural steels.
