Ductile Iron Casting Part Series 1
JHshukong
1. What is ductile iron?
Ductile iron is generally made of spheroidized and inoculated graphite, which effectively improves the mechanical properties, plasticity and toughness of cast iron, thereby obtaining a higher strength than carbon steel. Ductile iron is a high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. Based on its excellent performance, it has been successfully used in some castings with complex forces and high requirements for strength, toughness and wear resistance. Ductile iron has rapidly developed into a widely used cast iron material second only to gray cast iron. The so-called "iron instead of steel" mainly refers to ductile iron.
2. What is the application of ductile iron?
(1) Pressure pipes and accessories: Many industrial powers use ductile iron as the material for pipes and accessories, because it is more pressure-resistant than ordinary cast iron pipes during transportation, and it is more convenient and quick during construction, so it is wise to choose it as the material for pressure pipes.
(2) Automobile application: Ductile iron is mainly used in the generator part, gear, sleeve part, brake and special device part in the automobile industry. Like the well-known Ford company, almost all crankshaft parts are made of ductile iron.
(3) Agricultural machinery and construction applications: Generally, agricultural machinery needs a long life, and the various parts formed by ductile iron can achieve this. In addition, some bulldozers and cranes used in construction projects or road paving also use ductile iron.
(4) Valve manufacturing: Ductile iron is also mainly used in valve manufacturing. Ductile iron plays a big role in transporting liquids such as acids, alkalis and salts.
(5) General application: In addition to the above-mentioned representative uses, ductile iron is also widely used in the machinery industry, and can be used to produce some complex machine tool parts or heavy machine castings. Of course, it can also be used for lighter castings, giving full play to its tensile strength and good processing performance. Power tools such as wrenches and pliers also regard ductile iron as an ideal material.
