Steel Castings | Cast Steel vs. Cast Iron

There are few other types of metal components that are as beneficial as castings. Castings offer great design capabilities and produce high quality products that can be used in a wide range of applications for multiple industries.  Cast parts are formed by pouring molten metal into a mold cavity, allowing the metal to cool and solidify, and then removing the finished component from the cavity.  Two of the most popular types of metals that are used to create cast parts are steel and iron. While steel castings and iron castings may appear similar on the surface, each has its own mechanical properties that make them unique. Keep reading to find out which is best suited for your specific application!

Steel Castings vs. Iron Castings

Strength

Both steel and iron have high strength. However, cast iron typically has a better compressive strength than steel.

Corrosion Resistance

Iron has a better resistance to corrosion than steel. That being said, both metals will oxidize and begin to fade away in the presence of moisture. As a result, steel is actually a better option when seeking corrosion resistance because they are better at preventing oxidation.

Cost

While the cost for steel castings are initially more expensive than iron castings, they can end up being a more cost effective option when you consider long-term use and replacement costs.
