|---|---|
| Chemical designation | EN-GJL-250 |
| State | Graphite classification and fracture appearance in the tensile test |
| Etching | 3% Nital |
Cast iron with lamellar graphite, pure pearlitic matrix. The minimum tensile strength is 200-250 MPa (depending on wall thickness).
Graphite classification according to EN ISO 945-1:2019
- Graphite form I
- Arrangement E
- Guide number for size range: 5
The SEM images show a force fracture by tensile testing. A transcrystalline, ductile force fracture is present. Honeycomb fracture with pearlite lamellae is visible in the detailed images.
