Abstract Effect of different forging ratios on microstructure and mechanical properties of electrical die steel (H13) was investigated by metallographic microscope and SEM under simplex stretching and hot-forging condition. The results show that transversal impact property is much less than longitudinal in the same forging ratio. Following the forging ratio increasing, it makes merely influence on the transversal impact property, while the longitudinal impact property increases. The research shows that, the cross direction crack arrest property won’t be effectively influenced by forging ratio under simplex stretching and hot-forging condition. The forging ratio of electrical hot die steel should be controlled in four to six, which is most appropriate.
