Effects of Multiple Nitriding on the Quality of Nitriding in H13 Die Steel
The influence of the times of nitriding on the properties and microstructure of H13 die steel was analyzed through the comparison of hardness and microstructure.The results showed that with the increase of nitriding times,the thickness of nitriding layer increased,the hardness of mold increased,and the quality of nitriding tissue decreased.
