China produces HPM75 non-magnetic die steel

be packed with wooden frame

HPM75 is a nonmagnetic, high-hardness and free-cutting plastic die steel produced by special melting process, and it is an austenitic nonmagnetic die steel with nonmagnetic and high strength among HPM series steels. It can maintain stable austenite in various States and has very low magnetic permeability. HPM75 non-magnetic steel has the characteristics of high hardness, wear resistance, corrosion resistance and non-magnetism, which are comparable to many die characteristics such as stainless steel SUS304. Therefore, it is suitable for mold products with high requirements on corrosion resistance and wear resistance. The gas nitrocarburizing heat treatment can further improve the surface hardness and wear resistance, thus improving the service life of the die. HPM75 nonmagnetic steel is easy to work hardening, so it is suggested to work at low speed.

Properties and characteristics of HPM75 non-magnetic steel

HPM75 is a kind of high-strength austenitic non-magnetic die steel, which can maintain stable austenite in various states. Therefore, HPM75 non-magnetic steel has ultra-low permeability, high high temperature strength and hardness, excellent toughness and weldability, excellent mechanical properties and excellent wear resistance. HPM75 non-magnetic steel has been age hardened before leaving the factory, without any heat treatment; And the steel structure is uniform, suitable for precision etching machining.
