Abstract: The microstructure characteristics, the effects of cold rolling reduction and hightemperature annealing atmosphere on magnetic properties were researched in this paper, in order to develop the 0.20 mm thin gauge grainoriented silicon steel with qualified magnetic properties. The results showed that: the secondary recrystallization of the obtained 0.20 mm thin gauge grainoriented silicon steel was complete, and magnetic properties of the iron loss P1.7/50  and the magnetic induction J800  were 0.89 W/kg and 1.906 T respectively; and the surface textures of the hot rolled and normalized samples were mainly Goss textures, with the cold rolled texture mainly {001}〈110〉 and the annealed texture mainly {411}〈148〉, and the decarburized grain size was about 21.17 μm with very few Goss grain; and the suitable cold rolling reduction of the researched steel was 91.3 %, and the suitable atmosphere for high temperature annealing was 75 % N2.
