This study systematically investigates the microstructure， texture， mechanical properties， and magnetic properties of 0.20 mm thick non-oriented silicon steel for new energy vehicles under different annealing temperatures. It is observed that recrystallization had finished at 780 ℃. In the initial stage of recrystallization，λ fiber texture mainly formed in the cold-rolled shear bands， and some ｛114｝<841> and ｛112｝<110>， and ｛111｝<112> oriented grains are also formed there.The α* fiber texture of grains with orientation of ｛114｝<841>，｛112｝<241> and ｛100｝<120> is mainly formed in the other zones.When annealing at 900 ℃ and above，As the annealing temperature rises， the proportion of ｛111｝<112> components diminishes gradually， while the proportion of ｛100｝<001> components grows slowly. This augmentation in annealing temperature will foster the formation of λ fiber texture and impede the growth of γ fiber texture. Grain size increases with the rise in annealing temperature， yet the high frequency iron loss P1.0/400 initially declines before eventually rising to its lowest value.in the range of 920 ℃-960 ℃， and the grain size range is 108 μm-138 μm， which is also the best grain size range.As the annealing temperature rises， the strength diminishes gradually and remains nearly invariable in the 920 ℃-960 ℃ range.
