1.3242 | HS6-5-2-5 +AC
| Numeric designation | 1.3242 |
|---|---|
| Chemical designation | HS6-5-2-5 |
| State | +AC (completely soft annealed) |
| Etching | 3% Nital |
The microstructural images show a high-speed steel produced by powder metallurgy in the fully soft-annealed (+AC) initial state before hardening. The ferritic microstructure is very fine-grained with typical carbide precipitations.
The etching time with 3% Nital was 90 sec.
