| Abstract: | The influence of fast cyclic heat treatment on the life of punching and shearing mold made of Cr12MoV steel was studied.The heat treatment process,the microstructure and the performance of the steel were also introduced.The results show that after 4 cycles treatment,the ultra-fine grain is uniform,and the mechanical properties increase significantly.The life of the Cr12MoV steel oil pump sprocket fine mold increase by 3 times with the new heat treatment process. |
