Casting offers exceptional capacity for design detail. While there are many types of materials that can be used for castings, steel and iron are two of the more popular options. While cast iron and steel may appear similar on the surface, they are actually more different than you think. Let’s take a look at the difference between the two and why you should ultimately use steel castings for your next project.
Impact Resistance
One of the most significant advantages steel has over iron is its impact resistance. Steel is excellent for withstanding sudden impacts without bending, deforming, or breaking due to its toughness. While iron might be easier to work with, steel has an optimal mix of both strength and ductility, making it extremely tough. This makes steel desirable for many mechanical and structural applications.
Carbon Content
Iron and steel are both ferrous metals comprised of primarily iron atoms. However, pure elemental iron it too soft the be used in most applications. When mixed with carbon, it becomes harder and more useful. That carbon composition is the main distinction between cast iron and steel. Cast iron typically contains more than 2% carbon, while cast steel often contains between 0.1–0.5 percent carbon.
Should I Use Steel Castings for My Next Project?
Steel is the most widely used metal in the world and for good reason. Its impact resistance and durability make it a popular choice, especially in the casting world. At Ferralloy, we offer top quality steel castings that can be used for your next project. Contact us today to learn more.
