A he advancement of continuous casting process combined with modern techniques in secondary refining and controlled rolling and cooling made possible the production of a steel with a very good combination of properties for low carbon steels applications. This steel, called rimmed-equivalent, is being largely used in several products, with quality and cost advantages in relation to traditional ingot-casted rimmed steels.Rimmed steels have always had a great participation in the low carbon wire market, being applied for bolt manufacturing, low tensile galvanized wire and strapping wire. Despite being acceptable for these applications, they exhibit some inherent shortcomings like porosities, segregation, chemical analysis variations and a low yield due to conventional ingot-casting.
