NODULAR GRAPHITE CAST İRON
The usage of the ductile iron has increased because of the hing elongation characteristic in this way it is nominated instead of steel. According to easy production and production cast, GGG 40.3 of ductile iron, which has got the nearest elongation rate to steel, has began to be attractive for usage.
Nodular graphite cast iron (ductile iron, nodular) grey cast iron and nodular cast iron chemical components (except sulfur and manganese) mainly identical but Cast iron% 0.04-0.07 Mg or Ce, with the addition of graphite sphere instead of the shape of the plate is provided, this is nodular cast Iron, steel provides the most close to listing to show the mechanical properties.
