Spherulitic graphite cast iron (EN-GJS)

Spherulitic graphite cast iron, also known as nodular cast iron, is an iron-carbon-alloy with a high carbon share of up to four per cent.

Accordingly, the structure of graphite has a big influence on the mechanic characteristics of the material. It has a spherical form and due to this it is highly resistant to breaking, it is low in notch sensitivity and it has a high ductility. The last feature gives it also extremely high values at fracture strains.

The standardised naming of spherulitic graphite cast iron is EN-GJS.
