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 non-magnetic die steel in HPM series. Austenite is stable in various states and has very low permeability.

HPM75 non-magnetic steel has high hardness, wear resistance, corrosion resistance and non-magnetic properties comparable to stainless steel SUS304 and many other die characteristics; Therefore, it is most suitable for mold products with high requirements on corrosion resistance and wear resistance. Adopting gas nitrocarburizing heat treatment can further improve the surface hardness and wear resistance, and thus prolong the service life of the die.

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