What material is HPM75

HPM75 is a non-magnetic, high-hardness, free-cutting plastic die steel produced by special smelting process. It is a non-magnetic, high-strength Austenitic type non-magnetic die steel in HPM series. It can maintain stable austenite in various states and has very low permeability.


HPM75 non-magnetic steel has high hardness, wear resistance, corrosion resistance and non-magnetic characteristics comparable to stainless steel SUS304 and many other mold characteristics; Therefore, it is most suitable for mold products with high corrosion resistance and wear resistance. Using gas nitrogen carburizing heat treatment, can further improve the surface hardness, wear resistance, so as to improve the service life of the die.

HPM75 non-magnetic steel is prone to work hardening, so low speed machining is recommended.
