Henan Metals: Customized Cast Iron Products & Components - Your Ultimate Solution

Cast iron is a widely used material in various industries. It is classified into different types based on its properties and applications. The following are the common types of cast iron and their respective characteristics, applications, and scope.

Grey cast iron: Grey cast iron is the most commonly used cast iron and is known for its high strength and wear resistance. It has a tensile strength of up to 300 MPa and a yield strength of up to 200 MPa. This type of cast iron is suitable for applications that require high compressive strength, such as automotive engine blocks, cylinder heads, and transmission cases.

Ductile cast iron: Ductile cast iron is a type of cast iron that has improved impact resistance and toughness compared to grey cast iron. It is characterized by its ability to undergo plastic deformation without fracturing. Ductile cast iron is used in applications that require ductility, such as pipe fittings, pump housings, and valve bodies.

Enamel cast iron: Enamel cast iron is a type of cast iron that is suitable for high-temperature applications. It is characterized by its ability to withstand high temperatures without cracking or melting. Enamel cast iron is used in applications that require high-temperature resistance, such as furnace linings, boilers, and heat exchangers.

Chilled cast iron: Chilled cast iron is a type of cast iron that has improved hardness and wear resistance compared to grey cast iron. It is produced by cooling the casting more rapidly than usual, resulting in a harder and more wear-resistant microstructure. Chilled cast iron is used in applications that require high wear resistance, such as cutting tools, bearings, and pump parts.

Malleable cast iron: Malleable cast iron is a type of cast iron that has improved ductility and impact resistance compared to grey cast iron. It is characterized by its ability to undergo plastic deformation without fracturing and has a tensile strength of up to 250 MPa and a yield strength of up to 150 MPa. Malleable cast iron is used in applications that require ductility and impact resistance, such as automotive suspension components, valve bodies, and pump housings.

In conclusion, cast iron is a widely used material that comes in different types based on its properties and applications. Each type of cast iron has its unique characteristics, applications, and scope, making it suitable for a wide range of industrial applications.
