NASNM17
Nonmagnetic Soft Stainless Steel
NASNM17 is a high manganese austenitic stainless steel with a 17Cr-17Mn-7Ni composition. Nippon Yakin developed NASNM17 with improved workability by softening conventional nonmagnetic austenitic stainless steel. Nippon Yakin supplies this product in plate, sheet, and strip forms.

Work Hardening
Permeability
Relative permeability of the product will not change after the cold-working and will not be magnetized as well
Corrosion Resistance
NASNM17 provides corrosion resistance equal to standard austenitic stainless steel Type 304. Corrosion resistance is virtually unchanged even after heavy cold working.
Atmospheric Corrosion Resistance in Salt Spray Test
| Solution treatment material | No rust |
|---|---|
| 65% cold-rolled material | No rust |
Test conditions: 5% NaCl, 30°C for 7 days
Formability
In addition, formability is basically equal to that of Type.
304.
| Erichsen value (mm) | LDR (Limit Drawing Ratio) | |
|---|---|---|
| NASNM17 | 11.5 | 2.0 |
| NAS304 | 12.0 | 2.1 |
*Sheet thickness: 0.7mm
Heat Treatment
Heat treatment of NASNM17 is similar to that of conventional austenitic stainless steels. Typical heat treatment conditions are as follows:
Solution heat treatment: 1030–1150°C; rapid cooling
Solution heat treatment: 1030–1150°C; rapid cooling
Applications
Ornamental metal parts, Electronic components, Components in which a non-magnetic property is required.
