Castings investment is one of the most popular methods for producing long-lasting and high-quality components. Because casting allows for a high level of detail, no extra manufacturing or assembly is required. While a variety of materials can be cast, steel and iron are the most used due to their outstanding mechanical qualities in a wide range of applications.
Differences Between Cast Iron and Cast Steel
Cast iron is a reasonably simple material to work with because it pours smoothly and does not shrink nearly as much as steel. Cast iron is a great metal for architectural or ornate ironwork structures such as fencing and street furniture because of its flowability.
Resistance to Corrosion
When it comes to corrosion resistance, iron is superior to steel. That doesn’t rule out the possibility of corrosion in either case. Both metals will oxidize in the presence of moisture if left unprotected. They will eventually decay totally. The coating is advised for both steel and iron castings to prevent this.
Because of the lower material prices, energy, and labor required to manufacture a final product, cast iron is frequently less expensive than cast steel. While raw steel is more expensive, prefabricated steel is also available. Sheets, rods, bars, tubes, and beams are among them.
Advantage and Disadvantage of Cast Steel
It is known that the design flexibility of cast steel is its key feature. The designer of the casting has the greatest creative freedom. Complex forms and hollow cross-section pieces are now possible. Cast steel, on the other hand, has poor shake-suction, wear resistance, and mobility. When compared to cast iron, the casting performance is poor. In addition, the costs are higher than with regular cast iron.
The Advantage and Disadvantage of Cast Iron
Cast iron provides a number of advantages, including high wear resistance, machinability, and low notch sensitivity, to name a few. Its tensile strength and elongation, on the other hand, are extremely low. As a result, it can only make a restricted number of metal items that aren’t physically demanding.Steel and iron castings both have advantages and disadvantages. Depending on the application and physical features, either should be employed.
