SG Ductile Iron Bar GGG40

Ductile iron is specifically useful in many automotive components, where strength needs surpass that of aluminium but do not necessarily require steel. Other major industrial applications include pipework, oil well pumps, components in hydraulic rams for agriculture and yellow goods industries.

While most varieties of cast iron are brittle, ductile iron has much more impact and fatigue resistance. Weldability is considered fair to poor as compared to low carbon steels and advice should be taken from a welding consumable supplier.
