HPM75 non-magnetic steel mold characteristics:

HPM75 is a non-magnetic, high hardness, easy cutting plastic die steel manufactured by special smelting. Its die properties are as follows:

High hardness

Good abrasion resistance, good nitriding handling

Magnetic permeability (μ) =1.01, comparable to SUS304 non-magnetic

The hardness of 40-45HRC can be obtained by aging treatment at 700℃*5h

HPM75 non-magnetic steel application:

Magnetic plastic, magnetic field forming die

Wear resistant non-magnetic tools

Used in the manufacture of non - magnetic die steel in the electronics industry

Used for making high temperature glass molds

It can also be used for hot working die steel at 700-800°C

It is about 6 times longer than high manganese austenitic steel die life

HPM75 heat treatment:

l Solution aging heat treatment

l High hardness 40-45HRC can be obtained by aging treatment at 700℃*5h
