Ductile Iron Casting

National standard for cast iron ductile iron (GB1348-2009)
Production process (electric furnace production of ductile iron castings)
Pig iron into the furnace smelting - molten iron into the alloy ball \ inoculation treatment - casting cavity - box cleaning - heat treatment (if necessary)

Chemical composition for ductile iron castings must be guaranteed to reach the provisions of ductile cast iron grade and the corresponding mechanical properties is usually decided by the manufacturers themselves. Therefore, in the formulation of the technical requirements of ductile iron castings, generally do not put the chemical composition as the main technical requirements. China has formulated the "Ductile Iron Castings" standard (GB1348----1988), and clearly defined the requirements of ductile iron castings. In general, the technical requirements of ductile iron castings should include: mechanical properties, geometry and dimensions.

Advantages of Ductile Iron Casting :
- Ductile Iron Casting provides Higher Tensile Strength
- Less Deflection Under Load Conditions
- No Straightening Required in Most Instances
- No Problems With Hot Tears and Cracks
- Good Machinability
- Easier Feeding of Difficult Designs

Ductile Iron Casting is particularly well suited for :
- Valves
- Pump - Gears and Rollers
- Spring Hangers
- Suspension Parts
- Wheel Hubs
- Bearing Caps
- Hardware
- Universal Joints
- Threadless Connectors and Flanges
- Various Automotive and Agricultural Items.
