Advantages and Disadvantages of Carbon Steel (Mild Steel)

Carbon steel is just an alloy that has a combination of two constituents ― iron and carbon. It contains up to 2.1% carbon which may vary based on the requirement.

Also, it has other elements such as cobalt, nickel, chromium, titanium, tungsten and much more. American Iron and Steel (AISI) states that there is no minimum quantity of these elements present in the carbon steel. However, it demonstrates that the proportion of copper should be at least 0.40 percent.

Mild steel is the type of carbon steel that has lower levels of carbon in it. When the carbon content in the alloy is 0.05 to 0.309%, it is considered as the mild carbon steel. If the presence of carbon content exceeds the maximum limit of mild steel, it is termed as medium carbon steel which is further followed by high-carbon steel and ultra high carbon steel. Every type of carbon steel has its own benefits and drawbacks. It’s just that you need to consider your needs and accordingly pick one that suits your project the best.

If you’re working on a DIY or home improvement project mild steel will probably suit you best. Mild steel is also the most commonly sold sheet metal for DIY and home improvement projects. Here are some advantages and disadvantages of carbon steel in general.


  1. Efficiently Malleable

One of the most beneficial properties of mild steel is it can be bent, cut and twisted to create the desired shape easier than other metal. It is one of the reasons why carbon steel (mild steel) is popular in many industries from the manufacture of household items to structural applications to the DIY and home improvement project. The high level of demand makes mild steel a widely produced material and therefore a very affordable material.

  1. Weight

Compared to high carbon steel mild carbon steel is lighter. The proportion of carbon is the main influencing factor for the weight. Working with mild steel is, therefore, easier and is used for manufacturing auto parts, pipelines and i.e. fences and ornaments for homes and businesses.

  1. Greatly Affordable

While working on a low budget, mild carbon steel proves to be the best. It is an ideal material that keeps project cost as low as possible. While mild steel is relatively cheaper than other metals you will have to consider the fact that you may have to treat it to prevent it from corrosion.


  1. Comparatively Less Stronger

Mild steel is suitable for mechanical engineering and general purpose fabrication. Its strength makes it a terrific choice of material for the construction of cages, frames, fencing and in other applications where it will not be subjected to high stress. Therefore, it is preferred for making home and garden products that require low-stress.

  1. Limitation To Heat Treatment

Treating mild steel through heat mechanism can affect the carbon content. Usually, heat treatment is used to change the characteristics of steel. But once originally fabricated in the mill and cooled off there are no significant changes after heat treatment.

These are some of the benefits and drawbacks that affect the use of mild carbon steel. As every coin has two sides, so does mild steel. For you to make your project work perfect, you just need to ensure that fabrication is done by a reliable sheet metal fabricator.
