Abstract

The effect of recrystallization annealing temperature on the properties and microstructure of one-step cold rolled steel strip for shadow mask was studied. The results showed that there was no yield point elongation when the tensile tests were performed on the samples for annealing temperatures ranging from 750 °C to 810 °C. Moreover, increasing annealing temperature resulted in large grains, which was beneficial to the formability and magnetic property of steel strips. On the other hand, when the sample was annealed at 840 °C, its microstructure showed ununiformity with 0.04% yield point elongation, which was not good for the function of the shadow mask. Therefore, the proper recrystallization annealing temperature was about 810 °C for the present steel strip for shadow mask.
