Metal is involved in the majority of the world’s daily activities, but many of us are unfamiliar with the subtle, key differences between the main types. However, these intricacies are second-nature to the cast welding professionals at Nadler Welding & Repair Shop of Wentzville, MO. Here, this family-owned and -operated metal repair and fabrication team delves into the difference between cast iron and cast steel, so you can make an informed decision for a future project.

Cast Iron

The term “cast iron” represents any sort of iron made up of over 2% carbon, including gray, ductile, and malleable iron. Iron is often used in cast welding because it minimizes vibration and increases durability. You might encounter this type of metal in wheels, oil pans, hammers, and flywheels. Ductile iron is commonly used in pressure pipes, and agricultural and engineering industries. Grey cast iron prevents rusting and can carry heavier loads, while malleable and ductile iron have premium heat-resistance and ductility. Compared to cast steel, the manufacturing process for cast iron (especially ductile and malleable types) is more complicated, and therefore, more expensive.

Cast Steel

This type of metal is made up of less than 2% carbon, and it includes standard carbon steel and alloy steel. Compared to cast iron, this metal is much more versatile on the design front. Cast steel is more easily manipulated, so it can be formed into complicated shapes and even hollow pieces, and it’s excellent for cast welding. Depending on the intended application for your cast steel parts, it’s easy to alter the chemical composition to suit your needs, such as a humid environment or a heavy load. Since cast steel boasts uniformity in all directions, it makes finished products much more accurate and precise. Also, because it’s easy to work with, clients can benefit from shorter manufacturing times and lower prices. Compared to cast iron, cast steel’s fault lies mainly in mobility and wear resistance.
