Among the various production materials, there are many materials that differ by the tiniest bit in structure but are very different in functional use. I wonder if you have heard of ductile iron? Such a material combines the corrosion resistance of cast iron and the strength of cast steel, combining these two excellent properties into a better metal. In addition, ductile iron has excellent physical properties, good ductility and impact resistance. Today we mainly introduce the use of ductile iron.

 

What are the similarities and differences between ductile iron, cast iron and cast steel?

Compared to cast iron, ductile iron is stronger, but the corrosion resistance is the same. Compared to cast steel, they are comparable in strength, but ductile iron is more resistant to corrosion and oxidation, and costs less.

 

The use of ductile iron

 

We will mainly discuss the use of ductile iron from five aspects.

 

Pressure pipes and fittings: Many large industrial countries use ductile iron as the material for making pipes and fittings, because it can be more resistant to pressure than ordinary cast iron pipes during transportation, and it is also more convenient and fast during construction, so it is chosen as a The material of the pressure piping is sensible.

 

Automotive applications: Ductile iron is mainly used in generators, gears, bushings, brakes and special devices in the automotive industry. Just like the well-known Ford company, almost all crankshaft parts are made of ductile iron.

 

Agricultural machinery and construction applications: General agricultural machinery needs a long life, and the various components formed by ductile iron can achieve this. In addition, bulldozers and cranes used in some construction projects or road paving are also applied to ductile iron.

 

Valve manufacturing: Ductile iron is also mainly used in valve manufacturing. Ductile iron plays a great role in transporting liquids such as acid, alkali and salt.

 

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 castings for heavy machinery. Of course, it can also be applied to lighter castings to give full play to its own tensile strength and its good processing performance. Power tools such as wrenches and pliers also make ductile iron an ideal material.

 

What are the uses of cast steel and cast iron?

 

Cast steel and cast iron are the two major types of cast iron-carbon alloys. The difference between them is the carbon content in the alloy. Cast iron refers to an iron-carbon alloy with a carbon content greater than 2.14% or a eutectic structure in the structure. The cast iron used in industry is usually not a simple iron-carbon binary alloy, but a multi-component alloy with iron-carbon-silicon as the main element. Iron-carbon alloys with a carbon content of less than 2.14% are called cast steels. In addition, silicon, manganese, phosphorus and sulfur are also long-lived elements in cast steels.

 

Cast iron is the most widely used cast metal material in modern industrial production. Generally, it has been widely used in various sectors such as machinery manufacturing, metallurgical mining, petrochemical industry, transportation and national defense industry. Cast steel is widely used in many heavy and dynamic mechanical parts.
