Properties

GS circleDuctile iron is given by the spherical shape of the graphite, which gives the material the mechanical strength and toughness that, over the last decades, have enabled its use in numerous different fields.
Thanks to the microstructure controls, the family of ductile irons has a vast range of degrees able to satisfy various design requirements.
Zanardi Fonderie S.p.A. quality ductile iron has always been an excellent landmark for the market. Zanardi Fonderie is also specialised in the production of annealed iron, to ensure impact strength even at low temperatures (degrees EN-GJS-400-18-LT and GGG40.3). According to new version of EN1563, Zanardi Fonderie produce the new solid solution strengthened ferritic grades.
Reference standard: ISO 1083, EN 1563, FIAT 52215, ASTM A536.
