A high-manganese austenitic stainless steel, NAS NM15M was developed by Nippon Yakin with a composition of 17Cr-15Mn-4Ni.
Providing higher strength than conventional non-magnetic austenitic stainless steels, NAS NM15M does not magnetize even if cold worked with force. Nippon Yakin supplies this product in plate, sheet and strip forms.

| Workability | The hot and cold workability of NAS NM15M is basically the same as that of standard austenitic stainless steels such as Type 304, Type 316, etc. However, the fact that this is a high strength material must be considered in both cold and hot working. |
| Heat Treatment | The heat treatment is similar to austenitic stainless steels. The typical heat treatment is as follows: ・Solution heat treatment: 1050~1150℃; rapid cooling |
| Applications | Non-magnetic springs, gaskets, electronic components, and other components where magnetism is not desired |
