Numeric designation5.1301
Chemical designationEN-GJL-250
StateGraphite classification and fracture appearance in the tensile test
Etching3% 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.
