Cast iron with nodular graphite EN-GJS (GGG) - ductile iron

Cast iron with nodular graphite EN-GJS (ductile iron) is an iron-carbon material, the carbon part of which occurs mainly as graphite in globular form. This nodular graphite, which already exists as cast, characterises the material behaviour of cast iron with nodular graphite. The notch effect is minimal due to the spherical shape of the graphite. Thus, a high tensile strength is reached together with a good elongation.
