Strip Production

Effects of rare earth elements (RE) on modification of inclusions, the corrosion dynamic laws and the electrochemical properties of low carbon steel in Compact strip production (CSP) technology have been investigated with SEM, EDS and polarization curve measurements. The results show that the RE elements play an important role on the morphology and type control of inclusions and also reduce their size in low carbon steel. The corrosion is mitigated due to relatively compact corrosion products and the dispersion spherical RE oxides and/or oxy-sulfides inclusions with the addition of RE. Meanwhile, the electrochemical measurements show that the corrosion current density of low carbon steel with RE is lower than that of steel without RE. The corrosion resistance is improved to a certain extent by RE.

Hot Rolled

The effects of the rare earth (RE) element on the microstructure of a hot-rolled low carbon steel (B450NbRE) were investigated under different heat treatment conditions. It was found that the B450NbRE steel with ultrafine grained structure could be successfully prepared with a certain content of RE additive under an appropriate heat treatment temperature between A1 (717°C) and A3 (880°C). The corresponding critical temperature increases with decreasing the RE content. For instance, the critical temperature is 800°C for the RE content of 0.0140 wt.%, but it increases to 850°C as the RE content decreases to 0.0075 wt.%
