When it comes to casting, there is often little to no need for additional fabrication and assembly. That’s because it offers exceptional capacity for design detail. While many different materials can be cast, steel and iron are the two most popular due to their excellent mechanical properties for a wide range of applications. Let’s take a look at some of the differences between steel castings and iron castings.
Corrosion Resistance
When it comes to corrosion, iron has better corrosion resistance than steel. That doesn’t mean that either are impervious to corrosion though. When left unprotected, both metals will oxidize in the presence of moisture. Eventually, they will completely decompose. To prevent this, coating is recommended for both steel and iron castings.
Cost
Cast iron is often cheaper than cast steel because of the lower material costs, energy, and labor required to produce a final product. While raw steel is more expensive, there are, however, prefabricated forms of steel. Those include sheets, rods, bars, tubes, and beams.
Castability
Cast iron is relatively easy to cast, as it pours easily and doesn’t shrink as much as steel. This flowability makes cast iron an ideal metal for architectural or ornate ironwork structures such as fencing and street furniture.
