HPM75 Non-Magnetic Steel

HPM75 Non-Magnetic Steel - Non-Magnetic Steel HPM75 - HPM75 Hardness - HPM75 Non-Magnetic Steel Hardness HPM75HPM75 High Toughness, High Hardness Non-Magnetic Plastic Mold Steel What is HPM75 Material HPM75 is a non-magnetic, high hardness, easy-to-machine plastic mold steel produced by Japan Metal Co., Ltd. through a special smelting process. It is an austenitic non-magnetic mold steel with high strength from the HPM series. It maintains a stable austenitic structure under various conditions and has very low magnetic permeability. The high hardness, wear resistance, corrosion resistance, and non-magnetic properties of HPM75 non-magnetic steel are comparable to many mold characteristics of stainless steel SUS304; thus, it is most suitable for mold products requiring high corrosion and wear resistance. Gas nitrocarburizing heat treatment can further enhance surface hardness and wear resistance, thereby extending mold service life. HPM75 non-magnetic steel is prone to work hardening, so low-speed processing is recommended.
