The demand for cleaner steels increases every year. In addition to lowering non-metallic oxide inclusions and controlling their size distribution, morphology, and composition, clean steel requires control of sulfur, phosphorus, hydrogen, nitrogen and even carbon, and minimizing metallic impurity elements such as As, Sn, Sb, Se, Cu, Zn, Pb, Cd, Te and Bi. These requirements vary with steel grade...
Thermal treatments and thermo-mechanical processing routes were applied on a conventional structural steel (st37 steel: 0.12C-1.11Mn-0.16Si) for improvement of tensile properties and enhancement of work-hardening behavior. Full annealing resulted in a sheet with coarse ferrite grains and pearlite colonies arranged alternatively in distinct bands, which showed high ductility, low strength, and t...
