15MH -Nonmagnetic high hardness material-
Our original material ‘15MH’:Non-magnetic and high hardness material
15MH has Non-magnetic, Corrosion resistance, Abrasion resistance characteristics.
Please contact us if you need more details.
15MH Characteristic
Non magnetic |
Magnetic permeability Under1.01μ Prevent from becoming magnetized and adhering among metals. |
High hardness |
Surfece hardness HV500 For rotary shaft and revolving shaft which require Abrasion resistance. Possible HV700 with our original process. |
Corrosion resistance |
Same as SUS304 For using out of doors and seaside which require Corrosion. |

15MH processing specifications
We introduce an example of processing results. | ||
Size |
||
|
||
・Regarding the shape, composite processing such as long hole (about 10 times the diameter), sideways hole, milling cutter, step, groove, D cut etc is possible. ・We will also consider other processing at any time. ・Grinding is also possible according to required accuracy. |
||
15 MH is a material with high processing difficulty, but our company can grinding and turning with high accuracy as well as other materials.
Moreover, we also correspond to D cut · both sides D cut.
