A Ferrous Alloy is an alloy that has iron as its prime constituent and a small amount of carbon in it. It can also contain steel as its component. It plays an important role in industrial applications as it is widely used in manufacturing tools. Drill bits, which are cutting tools, are made by using carbon steel. Similarly, a Ferrous Alloy can be used for making engineered tools for specific uses.
The oil and gas industry requires proper tools that are used for different operations such as milling, drilling, exploring and so on. These tools are made by using a Ferrous Alloy or metal that is generally preferred for manufacturing heavy-duty engineering equipment. The main component of Ferrous Alloy is iron and a bit of carbon; however, the content of the constituents can vary from one metal to another. The common examples of Ferrous Alloy used in manufacturing of equipment for oil and gas industry are carbon steel, mild steel, cast iron and wrought iron.
Ferrous alloys were widely used as early as 1200 BCE, and continue to be used in a wide variety of applications. Some common ferrous alloys include:
- Carbon steel is used in structural applications.
- Stainless steel is a type of ferrous alloy that has high amounts of chromium added to enhance its resistance to corrosion.
- Alloy steel is often used in tooling and in applications that require high strength.
- Cast iron is often used in applications subject to wear because its high hardness provides it with excellent wear resistance.
- Wrought iron is relatively low in hardness and strength; it is used often for decorative purposes.
