Process Iron Normalization

Normalization is an annealing process applied to ferrous alloys to give the material a uniform finegrained structure and to avoid excess softening in steel It involves heating the steel to 2050 °C above its upper critical point, soaking it for a short period at that temperature and then allowing it to cool in air Heating the steel just above its upper critical point creates austenitic grains (much smaller than the previous ferritic grains), which during cooling, form new ferritic grains with a furt
