Malleable cast iron is produced from white cast iron, which is made from hot liquid iron with certain chemical components. The white cast iron needs to be treated by malleablizing, such as graphitizing or oxidation and decarbonization, then its metallographic structures or chemical components will be changed, so can become into malleable cast iron.
This type of iron is highly sought after for its flexibility and strength. Not only is malleable cast iron durable, but it can also be easily shaped and molded into many different forms.It begins with white cast iron, which is a hot liquid iron with specific chemical components. Through careful treatment, the white cast iron can be transformed into malleable cast iron.
What's remarkable about this process is that the metallographic structures and chemical components of the white cast iron are modified, allowing it to become malleable. This transformation is accomplished through methods such as graphitizing, oxidation, and decarbonization.
The resulting malleable cast iron can be used in various applications, such as in the construction of bridges, buildings, and machinery. This type of iron is highly valued for its strength and ability to withstand wear and tear.
Comparing with the gray cast iron, malleable cast iron has better strength and ductility, especially better impact resistance in low temperatures.
Comparing with cast steel, malleable cast iron has better abrasive resistance and shock absorption.
Comparing with the ductile iron, both of them have good strength and ductility, but malleable iron has better impact resistance, but ductile iron has better abrasive resistance.
