The HPM38 modified on the base of SUS420J2 belongs to 13CR stainless steel contained MO. Made by particular dissolved technology, it is more excellent in corrosion resistance. So it is most adapted for plastic die that requires for high hardness, high corrosion resistance and high mirror surface; what’s more, there is nearly no change of size after heat treatment, so it is also adapted for precision heat treatment, in addition, the good properties of immersion is good for keeping.


Application:
die for transparent product that requires for high polishing (household electrical apparatus, medical treatment, food); as well as rubber die requiring for corrosion resistance, such as parts for communication apparatus, parts for medical appliance and so on.

Characteristics:
good properties of polishing and corrosion; small size of heat treatment.
