Cast iron with lamellar graphite
|
Cast iron with lamellar graphite contains between 2.6% and 3.6% carbon, which is present as graphite in the form of fine lamellae. These lamellas run through the cast material in a fine-needled mesh and, due to the notch effect, produce its relatively low strength and brittleness.
Cast iron with lamellar graphite can be subjected to different heat treatments (such as curing, nitriding, tempering) to improve its properties. A high proportion of perlite in the basic structure is advantageous for heat treatments.

Cast iron with spheroidal graphite (ductile iron)
|
Cast iron with spheroidal graphite features microscopically fine spherical graphite excretions in the basic ferritic structure with a maximum carbon proportion of 4%.
The spherical geometry of the graphite deposits is achieved by adding low quantities of magnesium, cerium or calcium.
It is possible to modify the material properties with a subsequent heat treatment, e.g. through stress-relief annealing, pearlitisation, soft annealing and more.
