HS PH13 Hot Work Die Steel


The HS PH13 hot work die steel is also a good material for many customers.

As modified hot work die steel with high roughness and high isotropy, HS PH13 with its molding die design optimizes the alloy element ratio on the basis of traditional H13, reduces the content of harmful elements such as P and S, so that hot die steel H13 has good thermal stability and thermal fatigue resistance.
