1.2343 | X37CrMoV5-1 | AISI H11 thermal fatigue cracks
| Numeric designation | 1.2343 | AISI H11 |
|---|---|
| Chemical designation | X37CrMoV5-1 |
| State | thermal fatigue cracks |
| Etching | ungeätzt |
This forging tool shows considerable wear and tear due to thermal fatigue cracks. These reticular cracks occur as a result of high alternating thermal stresses, such as those that occur during forging or in die-casting molds. A clear oxidation of the crack flanks can be seen in the cross-section polish.
