Steel Castings vs. Cast Irons: Which Is Better?

Both cast iron and cast steel are ferrous materials that are primarily made up of iron and carbon. Both are excellent in investment casting in terms of qualities and are hence employed in various applications. They have excellent mechanical attributes, which will make it quite challenging to choose between the two. In this article, we'll look at the fundamental distinctions between cast iron and cast steel.

Differences Between Steel Casting and Cast Iron

Steel Castings

• In terms of impact loads, steel casting is superior.
• Steel casting is more expensive than cast iron.
• When compared to cast iron, cast steel has reduced flowability and shrinkage.
• Steel casting outperforms cast iron in terms of vibration damping.
• Steel castings have a higher melting point.
• Steel castings have a significant quantity of other alloying elements.
• The machinability and weldability of steel castings are both excellent.

Cast Iron

• In terms of corrosion resistance and mechanical wear resistance, cast iron is superior.
• Because of its excellent flowability and low shrinkage, cast iron is easy to operate in addition to that.
• Noise dampening qualities of cast iron are excellent.
• Cast iron is cheaper than steel castings.
• Iron and carbon are the two most essential elements in cast iron. Other components may be present in trace amounts.
• When compared to cast steel, machinability and weldability are inferior.
• The melting point is lower than steel castings.
