Abstract：With different grain size gained by different plastic deformation and recrystallization annealing process for Cr20Ni35 alloy, the influences of grain size on the resistivity of Cr20Ni35 alloy were studied, and the reasons were analyzed. Results show that the resistivity decreased gradually after different deformation, and the grain size does not have much effect on the resistivity, the reason is mainly due to the state of "K" is destroyed. But after annealing, the resistivity value rises again, and by observing its metallography, the result shows that the smaller the grain size is, the greater the resistivity will be.
