Ningbo parfect casting factory is a professional production of various types of cast steel, alloy steel, stainless steel, cast steel, alloy castings export-oriented enterprises. Let us talk about the difference between steel casting vs cast iron as follows:

Although the two are the same as the iron-carbon alloy, but because of carbon, silicon, manganese, phosphorus, sulfur and other chemical elements in different percentages, crystallization has a different microstructure, and mechanical properties and process performance shows many different .

For example, in the casting state, cast iron elongation, area shrinkage, impact toughness lower than cast steel; cast iron compressive strength and shock absorption performance better than cast steel; gray cast iron liquid flow better than cast steel, more suitable for Casting in the complex structure of the thin-walled castings; bending test, the brittle fracture of cast iron, cast steel for the bending deformation. And so on  Therefore, they are suitable for casting different requirements of the parts.
