Steel and iron are often interchanged as a result of confusion over their definition and applications.  However, when it boils down to the characteristics and chemical composition of the two, there are some noticeable differences.  Any quality alloy cast iron manufacturer would tell you that both cast steel as well as cast iron is used for building a number of equipment including parts of industry-grade machinery, automotive parts, kitchen utensils, pipes and ship anchors.  Here is a quick guide that would help you distinguish between cast iron and cast steel.

Carbon content: An important difference between cast iron and cast steel is their chemical composition. Both materials, technically, are made of iron. But the difference lies in the carbon content. Cast Iron has a comparatively higher percentage of carbon content, approx 0.1 -0.5% of carbon. Cast Iron, on the other hand, contains 2% of carbon content.

Cast ability: The unique chemical properties of cast iron make it a better candidate for casting than cast steel. Both materials exhibit the same melting point which drops to a temperature of little 2000F or higher. But cast iron is popular for its fluid nature. This means it can be easily poured into moulds of any size or shape.  If the alloy cast iron casting manufacturer is experienced enough, the casting can be done even using a minimum quantity of cast iron, due to low shrinkage rate. On the contrary, cast iron is difficult to pour into different moulds. Great attention is required in the casting process as it has a much higher percentage of shrinkage and tendency to react with other metals.

Resistance to sudden impacts: Cast steel is advantageous in one aspect its ability to resist sudden impact or duress. Cast iron, on the other hand, characterises low ductility; it is slightly brittle when exposed to rapid stress or strain.  However, cast steel can return to its original shape when subjected to a high amount of pressure or force. This makes cast steel preferable over cast iron in the manufacture of auto parts and machines and in building & civil construction.
