What Are The Differences Between Cast Iron And Cast Steel?

Iron and steel, along with their alloys, dominate the ferrous metal industry. These have extensive applications in the manufacturing and engineering sector. Most metals, ferrous and non-ferrous, are used after casting. Casting is the process of melting the metals and then pouring them into moulds to get the desired shape. Iron and steel have been prevalent in the casting industry as well.

A Brief Comparison

Even though both the metals comprise of iron and carbon mixed with alloys, they perform quite differently. The prime difference between them is the percentage of carbon each contains. Cast iron contains more than 2 per cent of carbon, while cast steel only includes 0.1 to 0.5 per cent of carbon. This makes a huge difference in the characteristics they display, as the carbon gap is significant.

Cast iron has been preferred overcast steel a lot of the times because it is better than steel in a lot of aspects. To begin with, cast iron is more comfortable with producing. The casting ability is better. It melts at a lower temperature than steel and also flows better. Shrinkage is also smaller in cast iron. Cast iron has also been in good light because it has a higher compressive strength. After it has been cast, machining it to make it better is even more comfortable in comparison to cast steel, which is harder to handle. This makes the overall cost lower. Additionally, raw steel is more expensive, to begin with, so everything piles up quickly.

Both cast iron and cast steel perform equally when it comes to corrosion and wear resistance. Cast iron may have a slight advantage, but it isn’t something significant. One of the reasons cast steel is in the market is because of its impact resistance. Cast iron offers excellent impact resistance and can handle an impressive amount of stress and strain. Thus, the machinability is an essential determinant for the viability of the end product. The final application depends on this to a great extent.

It is quite evident that cast iron outweighs cast steel in most of the departments. Still, finding the right alloy cast iron casting manufacturer in West Bengal can be a lot trickier. It will help if you choose service provider among the top contenders in the market. With years of experience in the industry, their products will not disappoint you.
