Basic Info

What material is HPM75 non-magnetic steel

With the development of industry, the application of non-magnetic steel is more and more extensive. Non-magnetic steel also plays an important role in various fields. When we are making semiconductor IC sealing plastic mold, we have encountered material selection problems. After several twists and turns, we finally choose HPM75 in non-magnetic steel materials. So HPM75 is a kind of what kind of material? Next, we will introduce this material in detail from all aspects.


What material is HPM75 non-magnetic steel?


HPM75 is an atypical plastic die steel with weak magnetic properties, high hardness and easy cutting. In the HPM series steel, it is also a high strength Austenitic non-magnetic die steel, which can maintain stable austenite in various states and has a very low permeability.

HPM75 non-magnetic steel is also suitable for mold products that require high corrosion and wear resistance. If gas nitrocarburizing heat treatment is adopted, the surface hardness and wear resistance can be further improved, so as to prolong the service life of the die.

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



HPM75 has no magnetic properties

Relative permeability μ R <1.005

Magnetic field gradient δ B≤0.04μT





HPM75 non-magnetic steel fatigue strength

100,000 to (at least) +/-65KSI

Measured more than 300,000 times



HPM75 non magnetic steel corrosion detection

Perform ASTM A262 E and pass the test.

Perform ASTM A262 A method and pass the inspection.

Properties and characteristics of HPM75 non magnetic steel

HPM75 is a high strength Austenitic shape 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 aging hardening treatment, without any heat treatment; The uniform structure of steel is suitable for precise etching processing.
