1.2379 | X153CrMoV12 with crack in the HAZ
| Numeric designation | 1.2379 |
|---|---|
| Chemical designation | X153CrMoV12 |
| State | crack in the HAZ |
| Etching | 3 % Nital |
In the left area of the picture, there are still unforged shrinkage cavities. This insufficient degree of forging was the cause of the crack in the HAZ (heat-affected zone).
