What is the normalizing process of steel?

Normalizing process of steel differ from the annealing process of steel with respect to heating temperature and cooling rate. In case of normalizing the steel is heated to a higher temperature and then removed from the furnace for air cooling.See all results for this questionWhat is the microstructure of steel?The microstructure produced by normalizing, depending upon the carbon content of the steel, is pearlite (eutectoid), pearlite in a ferrite matrix (hypoeutectoid), or pearlite in a commentate matrix (hypereutectoid). Cooling in air results in a fine pearlite with improved mechanical properties compared to the full annealing process described above.See all results for this questionWhat is normalized microstructure?The normalized microstructure is not presented here, but normalizing treatments usually result in finer grained and more homogenous austenite, which will result in a finer grained pearlite and ferrite microstructure, with perhaps a finer pearlite carbide spacing.See all results for this question

Steels are generally heat treated in order to achieve desired changes in their microstructure and mechanical properties.Normalizing Process for Steels IspatGuruApr 10, 2014 · Normalized steel has higher hardness and strength than annealed steel due to the following reasons. The amount of pearlite in the normalized steel is more than that in the annealed steel having the same carbon content, due to the shifting of the eutectoid composition to a lower value. The dispersion of pearlite and ferrite phases is finer.
