The HS PH13 hot work die steel is also a good material for many customers.
As modified hot die steel h13 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.
