Process Optimization and Product Metallurgy in Long Products (Room 412)

07 May 19
2:00 PM - 2:30 PM

Tracks: Metallurgy - Processing, Products & Applications

The recent technological integration of both the process and physical metallurgical advancements of value-added niobium (Nb) -microalloyed long products has evolved into the development of low-cost, high-quality, low-manganese steels for long product end-user requirements. This innovative metallurgical connection is validated by the market demand for improved quality, improved steel ductility, robustness and toughness in both the automotive special bar quality and construction steel sectors. The complementary refinement of the microstructural grain size through MicroNiobium additions and reduced manganese (Mn) levels in long products improves the robustness of the steel to better accommodate process metallurgy variations.
