Back (Fe-Base)

1.3242 | HS6-5-2-5 +AC

Numeric designation1.3242
Chemical designationHS6-5-2-5
State+AC (completely soft annealed)
Etching3% 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.
