1.7225 | 42CrMo4 +I, intermediate-stage heat-treated
| Numeric designation | 1.7225 |
|---|---|
| Chemical designation | 42CrMo4 |
| State | intermediate-stage heat-treated |
| Etching | 3% Nital und PAG QT² |
The microstructural images show the 42CrMo4 following isothermal hardening. A bainitic microstructure is present.
The hardness is 446 HV 10.
The etching to reveal the former austenite grain size using our PAG QT² worked very well.
