7 mn15cc2al3v2wmo introduction:
7Mn15Cr2Al13V2WMo non-magnetic die steel for short 7Mn15 non-magnetic die steel
7MN15CR2 has non-magnetic plastic die steel. With high hardness, wear resistance, corrosion resistance and non-magnetic as stainless steel SUS304 pig multi-die characteristics, so the most suitable for corrosion and wear resistance requirements of mold products. In addition, it also has good heat treatment performance. 7MN15 non-magnetic steel is prone to work hardening, and should be processed at low speed.
7 mn15 features:
L Permeability (μ)=1.01, it has the same nonmagnetic property as SUS304
L High hardness 37-41hrC can be obtained by aging treatment at 700℃*5h
L Good heat treatment performance, suitable for precision die
L Good wear resistance, can be nitriding treatment
7 mn15 USES:
L Used for manufacturing non-magnetic molds in the electronics industry
L Non-magnetic die for magnetic material factory
L Used to manufacture high temperature glass mold
L also used in hot working dies at 700-800℃
L More than high manganese austenitic steel die life about 3 times
7MN15 heat treatment:
L Solution aging treatment
L High hardness 37-41hrC can be obtained by aging treatment at 700℃*5h

No magnetic die steel 7Mn15Cr2Al3V2WMo is mainly used in permanent magnet material mold production and the demand for hardness and wear resistance of permanent magnet motor electrical parts, the amount is not large, but there is demand.
Sixth, in the future, there will be a large demand for non-magnetic tube billet non-magnetic round steel in the application of c-type embedded channel steel for high voltage cable used in underground pipe corridors of urban construction and the application of roll screen in metallurgical sintering pelletizing equipment.
