Black Carbon Steel vs Carbon Steel: What’s the Difference

Black Carbon Steel vs Carbon Steel

When it comes to steel, there are a lot of different types that can be used for various applications. One of the most popular types is carbon steel, which is available in two variations—black carbon steel and regular carbon steel. But what makes these two types different from each other? Let’s take a look.

Black Carbon Steel vs. Carbon Steel

The difference between black and regular carbon steel lies in the production process. Black carbon steel is created through a process called hot rolling. High temperatures heat the steel beyond its recrystallization point in this process and make it more malleable. The steel can be easily manipulated into different shapes without losing strength or durability.

On the other hand, regular carbon steel is created through a cold rolling process instead of hot rolling. In this method, the temperature remains below recrystallization, so the metal does not become as malleable as black carbon steel would be after hot-rolling. As such, regular carbon steel tends to have higher tensile strength than black carbon steel but lower ductility—that is, it’s not as easy to shape or form into different shapes without breaking or cracking.

Another critical difference between these two types of steel is their appearance; black carbon steels tend to have a darker matte finish due to their increased malleability compared with regular carbon steels, which usually have a brighter finish due to their higher tensile strength. Additionally, both types of steel can be galvanized (coated with zinc) for corrosion resistance. Still, black carbon steels require less coating than regular ones due to their increased surface area resulting from increased malleability during manufacturing processes.

  • Black carbon steel is made by adding a small amount of carbon to the steel.
  • Black carbon steel is more durable than regular carbon steel.
  • Black carbon steel is less likely to rust.
  • Black carbon steel is more expensive than regular carbon steel.
  • Black carbon steel is not as strong as regular carbon steel


For those looking for an affordable yet durable option for projects requiring metal components, black and regular carbon steels are excellent choices; however, depending on your application needs, one type may be better suited than the other depending on its tensile strength or flexibility requirements. To ensure you select the best type of metal for your project, it’s essential to understand how these two types differ in the production process and physical properties before making your final decision!
