Non Magnetic
Austenitic stainless become magnetic by work-hardening. (originally non-magnetic)
It’s difficult to combine both characteristics of Non magnetic and Abrasion resistance.
Non magnetic and Abrasion resistance
※Our original material ‘15MH’ has Non-magnetic and Abrasion resistance characteristics.
The above chart of Non-magnetic and Abrasion resistance of 15MH.
