The effects of Sn addition on core loss and texture of non-oriented electrical steels were investigated.Experiments revealed that the core loss of non-oriented electrical steels could be obviously decreased and the intensity of {111} texture and {112} texture of final annealed specimens could be markedly reduced by Sn addition.The reasons for reducing core loss and the intensity of unfavorable texture were analyzed. The effects of Sn addition on core loss and texture of non-oriented electrical steels were investigated. Experiments that the core loss of non-oriented electrical steels could be obviously decreased and the intensity of {111} texture and {112} texture of final annealed specimens could be markedly reduced by Sn addition. These factors for reducing core loss and the intensity of unfavorable texture were analyzed.
