Ductile iron is a cast iron material in which graphite is distributed in a spherical shape through spheroidization and inoculation treatment. Its comprehensive properties are close to steel, and its strength, plasticity, and toughness are superior to ordinary gray cast iron. It has been widely used in multiple industrial fields.
Performance Characteristics
Mechanical properties: The tensile strength, yield strength, and elongation of ductile iron are superior to ordinary gray cast iron, and even comparable to some steels. For example, ductile iron (ADI) that has undergone isothermal quenching treatment has bainite and residual austenite structures, significantly improving tensile strength and wear resistance. It can replace forged steel in the manufacturing of automotive towing hooks, bushings, and crankshafts, achieving a weight reduction of more than 10%.
Wear resistance: Ductile iron has better wear resistance than non alloy steel and is suitable for manufacturing wear-resistant parts.
Casting performance: The casting performance of ductile iron is better than that of cast steel, and it can cast parts with complex shapes and uneven wall thickness.
Processing performance: The processing performance of ductile iron is almost comparable to that of gray cast iron, and it is easy to cut and grind.
Corrosion resistance: In most municipal applications such as water, salt water, steam, etc., ductile iron has higher corrosion resistance and oxidation resistance than cast steel.Application Fields
Automotive industry: Ductile iron is widely used in key components such as automobile crankshafts, camshafts, gears, clutch plates, hydraulic cylinder blocks, etc.
Mechanical industry: Ductile iron is used to manufacture mechanical parts such as hydraulic components and machine tool beds.
Municipal engineering: Ductile iron pipes (DIP) have excellent corrosion resistance and sealing properties, and are widely used in urban water supply, drainage, gas and other fields. Taipei and other cities preserve century old pipelines and extend their service life through lining renovation methods.
Other fields: Ductile iron is also used in the manufacturing of agricultural machinery, mining machinery, chemical equipment and other parts.
