Advantages of Ductile Iron Castings
Ductile iron castings combine the processing advantages of a low melting point, good fluidity and machinability with many of the engineering advances of steel including high strength, ductility and wear resistance. These qualities allow for a much higher tensile and yield strength as well as a lower damping capacity.
Microstructure of Ductile Iron
Ductile iron, also referred to as nodular iron or spheroidal graphite iron, has an unusual combination of properties obtained because the graphite occurs as spheroids rather than flakes as in gray iron. This mode of solidification is obtained by adding a very small but specific amount of magnesium to molten iron. The allowable content of minor elements that can interfere with the graphite spheroid formation in the base iron is severely restricted. The added magnesium reacts with the sulfur and oxygen in the molten iron and changes the way the graphite is formed.
Tensile & Yield Strength
Ductile iron has a minimum tensile strength of 60,000 psi and a minimum yield strength of 40,000 psi. Ductile iron’s commonly established properties are tensile strength, yield strength and percent elongation. Because of the nominal and consistent influence of spheroidal graphite, the tensile properties and the Brinell hardness of ductile iron are well correlated.
Low Damping Capacity
The relative ability of a material to absorb vibration is evaluated as its damping capacity. The quelling of vibration by converting the mechanical energy into heat can be important in structures and devices with moving parts. Ductile iron has a relative damping capacity of 0.14, significantly less than that of a similar gray iron part with a damping capacity of 1. Still, ductile iron compares favorably versus steel alloys in terms of damping capacity.
Ductile Iron Casting Applications
Due to the increased strength and ductility of ductile iron, it is used in more engineered applications such as:
- Value Bodies
- Compressor Valves
- Sprocket Wheels
- Hydraulic Valves & Cylinders
- Structural Brackets
- Cable Drums
- Exhaust Manifolds
- Machine frames
- Gear Boxes
