Normalizing of hot rolled bands results in better magnetic properties (lower iron loss and higher flux density) than non‐normalizing, which is caused by the fact that normalized steels show larger final grain size, higher volume faction of cube texture, and lower volume fraction of γ fiber than non‐normalized ones. Antimony and tin alloyed steels provide the best magnetic properties among the test steels and have bigger grain size than boron steel. The first group also has a higher fraction of (100)‐fiber and a lower share of γ fiber than the boron steel. However, the effects of these elements on textures with or without normalizing are minimal. The texture factor (TF) has a stong influence on the magnetic properties of normalized NO steels, while the magnetic properties improve with a decrease in TF, but this effect is not so pronounced for non‐normalized materials.
